30 Pack Thin Cork Sheets 4 x 4 Inch Cork Backing Sheets Mini Backing Self-Adhensive Cork Squares for DIY Coasters

I had some 4x4 perler bead coasters I made a long time ago, and finally decided to get a backer for them just to make sure condensation didn't leak through the bead holes and get on a table. I saw these (very lucky they were the exact size I needed) and they were very easy to put on. When you first put them on, if you make a mistake you can easily remove and re-position to make it right. No issues with them peeling off on their own, and have had them on for about a month or so now. If you needed to tear them off for some reason I'm sure you could. I did make sure to put good pressure on them after getting them on right for a little bit of time (put some heavy books on them) to make sure it adhered well, but extremely happy and will get again when I need more. One note (that doesn't affect me at all but may you) is that I think the size is nominal. The actual size I got was 3-15/16" x 3-15/16".

What a deal on the price!!! 36 cents/square!! These cork squares are great for DIY coasters! Super sticky for great adhesion! Easy to peel off the back and adhere. Will be ordering more for future DIY projects!

I made a set of coasters and purchased the foam squares to go on the back of them. They work great! No peeling, they fit securely!

So it depends what you use these for, we wanted to use them on the bottom of round coasters that we made. Unfortunately they kind of crumble when you cut them into a different shape. Also, we added a different adhesive because they stuck, but I felt that over time they would come apart. So they aren’t bad or anything, just have to figure out a better way to cut them so they don’t crumble so much. But if you use them as is, I’m sure they will work just fine.

Easy to use Sticks well and looks good. I used a paper cutter to get a good straight line when I had a smaller tile.

I was really really hesitant about buying these because of the negative reviews but my kids wanted to make coasters with the cricut and gift them out to friends family and neighbors teachers just about everybody on our list this year being stuck at home our state going into another lock down seem like the perfect project. I spent a good week looking at different self adhesive cork backing’s for the tiles I got and I finally decided to go with these despite what people were saying they are extremely sticky I had no problems no extra glue was needed nothing they’re also thick much thicker than the cork on my store-bought coasters that I have in my house and I mean come on it’s $11 for 30 of them you can’t beat that.

These worked perfect for my tile coasters, the right size, and went on easily..they aren't real thick which I liked and have had no problems with them sticking..I'd definitely buy more

Used these to back tile coasters. The 2mm is just right. Don't get anything thinner. Well made, consistent quality.

Delivery took longer than expected but the quality of the product is good. Works great for my projects. They are easy to peel and stick.
