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

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

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 was3-15/16" x 3-15/16".

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.

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.

The media could not be loaded.  I used these cork sheets for the back of these DIY coasters I made. They have a white paper you peel off and just stick it to the back of the coaster. I gave the coasters as gifts and forgot to take pictures of the cork on the back so I shared the video

I have ordered these multiple times and they work great for my 4x4 tile coasters. Only bad thing to say is that they are not always consistent with the count. Sometimes there are 30 as advertised and sometimes there are 29...

Works great for coaster bottoms. Will buy again.

Great value , easy to use, fits a little over the edge though.
