I put this note on my RV 4 weeks ago, drove for 4 hours one time and still going strong, amazing
I bought these for use on a rural route i stuck one on the windshield of my pickup where it was out in snow, rain, and sun... it stayed for 2 weeks solid. I do understand the thing about the texture but honestly once you get used to it its kind of nice. I prepared a gift of these with a black bic marker pen and my co-workers adored it and keep asking me when I am ordering more. These are definitely worth the extra bit of money if you want something rugged.
It's weird to write a review for Post-its, so I'll just say these are exactly what they say they are, extremely durable and resistant Post-Its
Love these. So sticky you can move over and over and over. Stick to everything.
Being an aficionado of Post-it notes (I think I have one of every type). I dove on the opportunity to try out “Extreme Post-its”. Based on the Amazon description, I did not see any warnings for use in “normal” versus “extreme” conditions, so I used some in the office.
OFFICE USE: GEL PENS WILL SMEAR UNTIL THEY DRY, WHICH TAKES A WHILE
They do not work well with Gel pens, which I tend to use exclusively in the office. I could not figure out how my hands were getting so ink covered and it was because ink on the post it was not drying and transferring onto my hands (I’m right handed, so this is not a common occurrence).
Sharpie, ballpoint pens and pencils did not seem to have this issue.
However I recently had some uses labeling tins and jars full of nails and screws (with a sharpie), so I will try these out head to head with the Post-its I already put there. Will update this review when I do that.
Ironically as messy as the post it notes were with the gel pens, once they dry, they are pretty durable. I accidentally left a post it note in my pants pocket, through both a wash and dry cycle only to find it in the dryer. Not only was the post-it note intact, but it was readable. I know from prior experience, that most post-its don’t make it through intact in the washer and dryer, much less readable
A colleague of mine who has been doing some major renovation at her house, when seeing these post-its, happily walked away with a pad of these to put on her walls where some changes needed to be made. I will let you know how that works out.
OBSERVATIONS SO FAR:
Once the ink sticks it’s there until you take it off. The paper is really durable. The sticky section is also very aggressive. I would not put on paper, or any fragile surface. Day to day use around the house with this in mind is great. My cat could not pull one off the mirror (my reminder of an early morning dentist appointment).

Description
When conditions make communication tough, Post-it extreme notes make leaving notes and reminders simple, so you can get the work done. Made with dura-hold paper and adhesive, these notes will hold up in hot, cold and wet conditions. They stick to tough and textured surfaces like concrete, raw and painted wood, and tile. Make sure your message is seen with a note that sticks in tough conditions. This paperboard pack includes 24 pads of Post-it extreme notes in Orange, Green, Mint and Yellow. Each pad has 45 sheets.
These solve the achilles heel problem of post-its -- they don't necessarily stick to everything. These things do with a vengeance. They stick (and hold up to) dang near anything you can throw at them. They aren't made for 'long-term' post-it noting I don't believe and I'd still use a piece of tape for that.
I use them in the garage, outside, in the shop, and pretty much anywhere else a normal post-it won't hold up or I want to be sure that i don't lose it. These are also great for things like engine teardowns where you can label your piles o' greasy bolts on your work bench, etc. It really is a game changer.
That said, there are some limitations I wanted to point out:
1 - These come with a warning about "removing paint" and other such stuff from otherwise-delicate surfaces. I'm not brave enough to test this but I believe it's worth pointing out so you know that you'll still need two sets of post-its; one for indoor use and one for outdoor.
2 - They won't stick to wet and super-dusty stuff -- this one is a bit of a no-brainer, and it's not really the post-its issue, because there's only so much it can do for a poor surface but they still aren't made of magic. If you're in super-wet conditions and hoping to stick post-its to things, it needs to be dry first.
Beyond that, they're fantastic and work exactly like you're hoping!
QUICK SUMMARY: Stickier than regular Post-It notes (that's a good thing). Waterproof when used with Sharpies.
BACKGROUND: I've had poor experience with Post-It notes (and unbranded similar) when I use them with poster-sized pads of paper during training classes I periodically do. Regular Post-It notes too easily come unstuck from the poster paper and they'll fall to the ground - very frustrating during a training class!
These "Extreme" Post-Its are stickier than regular Post-It notes. These stick to the large pads of paper I use to write on, and they don't fall off the poster-paper. Yet, they can still be removed pretty easily, too.
That they're meant for "extreme" conditions -- outside conditions, watery conditions -- makes them more versatile to use in one sense. And if they get completely drenched, once dry, the adhesive remains on the Post-It note and it can be re-applied somewhere else.
One big caveat to note! These "Extreme" Post-It notes work best with Sharpie felt-tipped pens. You can use them with pencils, too, although I think the pencil lead is too washed-out compared to using a black Sharpie. If you use, say, a G2 gel pen (as I did), it's a mess and the ink won't saturate properly. So, have Sharpie pens available if you're going to use these pens. Dry-erase markers also work okay, too.
Nice assortment of colors. I'm looking forward to my next training class where I can FINALLY use Post-It notes that won't fall to the ground! Recommended!
These well suited to extreme conditions. I used them working on my senior design project. Not only was the project a fluid moving design, but it was constructed in garage bay on the waterfront of a river. Humidity and wind were a constant issue. I needed to have notes on each section as my partners didn’t often have our schedules coordinated. They needed to stay in place and be legible for at least 3-4 months in some cases. During our time there was a lot of saw dust, dirt and fluids sprayed around. Each note was easily readable and stayed affixed to the piping. One thing I didn’t test out was movability, I only needed to relocate a few of the notes and only once. Those few I did move, didn’t fall off but they were more protected areas so there wasn’t much of a test to the adhesion.
The notes themselves are not as thick as the normal Post-its, making them flimsy and easily imprinted. I was able to read the impressions 3-4 notes down, instead of the normal 1-2 notes of a desktop pad. They’re made from a waxy, plastic like material that is more durable even with is flimsiness. It feels and has the texture of painter’s tape but is significantly hardener to tear in half. You can do it with your bare hands, but you must do it intentionally and with some effort.
I was able to legibly write on these notes with ballpoint pens, fine tip sharpie, a sharpie pen and standard pencil. When I used a wider tipped sharpies or off brand permanent markers, there was smudging. Didn’t even try the gel pens, it’s the only thing specifically stated that doesn’t work on these notes. All the colors in this pack work well with standard blue or black ink, there is enough contrast that the inks stand out well.
Post-it Extreme Notes, Water Resistant, Dura-Hold Paper and Adhesive, really do last in harsh conditions. These Post-it- Extreme Notes are for use in conditions where regular notes would curl up and die. That means tough conditions such as inside/outside, hot and cold conditions, wet (as long as it was dry when applied), rough surfaces such as finished and unfinished wood, brick, concrete, tile, and others. I found if I could get the note to stick on a surface, it was good to go. And I didn't find a surface where it wouldn't stick. They can be moved from surface to surface when they and the surfaces are dry. They work in good conditions too.
It is best to use a permanent marker like a Sharpie to write on the note. Regular pens, gel pens, and such don't last well. Don't bother with a pencil either as the marks are too light and hard to read on the Extreme Note surface.
As an extreme test, I wrote several notes and posted them on some different surfaces on my patio when I knew it was going to rain. We don't get much rain but we do get heavy mist/foggy conditions. I really wanted to test them in rain and we did get a rainy day early this month. I stuck the notes to a fence post (unfinished wood), to a vinyl barbeque cover that really got rained on, and a patio table umbrella. The notes all survived where I placed them and once they were dry again, I tried moving them to other spots. They stuck to the secondary spots just as well. I was pretty impressed.
The Extreme Post-its have a textured, rather hard surface and come in assorted bright colors. They measure 3" x 3" so there is a decent amount of writing space. The adhesive is outstanding and lasts well. These post-its are a great solution to a continuing problem of notes lasting in dicey conditions.
When I got these, it came with a note to try them places that you would not normally use post-its. So I decided to try two news places out even though I really just wanted them in my classroom.
1. I tried this out on the dashboard of my car. All of us want to stick quick notes on the car so that we don't forget to go pick something up. It's a great place for a grocery list because it is always right there. Unfortunately, since it is also dusty, has air moving over it a lot, and is generally an odd texture, most sticky notes do not stick there. This one was pretty good. I stuck our garage is not temperature controlled, and we park both cars in it, so it is used frequently. We have tried using labels on the plastic storage containers in the garage with minimal success. They often fall off and writing on the plastic with black sharpie fades quickly. Again, we labeled the boxes with these and did not change any routine. So far it has been about 2 weeks, and none have fallen. They are even gathering some dust and not really fading or moving. Hopefully, they will stay stuck for a long period of time instead of having to consistently retape something in place.
Finally, I took the rest to my classroom. We do a lot of activities where the kids write on a post-it and then stick them on charts around the room. They work great for this task but may be a bit too expensive for the average teacher looking for stickies. If you wanted to get something that would stay stuck through a week or more, then it may be worth it, but otherwise not.
