Blisstime 36 Self-Adhesive Cork Sheets 4"x 4" for DIY Coasters, Mini Wall Cork Board with Strong Adhesive-Backed

I make ceramic coffee coasters as a hobby and you always need something on the back to keep the ceramic from scratching a surface. These cork self adhesive work great. These cork backings are 2mm and I think next order I will order 1mm instead. The extra thickness is not needed. These cork backings fit perfect for a ceramic tiles measuring 4 1/2 X 4 1/2 that I buy from Home Depot but will need to be cut down a little for the 4 X 4 tiles that are sold at Lowes. So far the adhesive seems to be holding up very well. I'm very happy with this purchase.

These work great for my shower tiles that I bought to use as coasters. Cheapest coasters ever. These keep the bottoms of them nice so they do not scratch surfaces. The bottoms of my tiles are not perfectly flat but these are thin enough that they follow the surface when you push it on.

arrived as expected; good adhesion; right size for my project; good value

It could be a little thicker cork but it works just fine.

These are great. I cut over 150 squares by hand and added the adhesive until I found these.. This was a time saver and the quality is excellent. Thickness is nice worked very well for my project.Highly recommended.

These worked perfectly to turn some beautiful stone tiles I found at ReStore (for a dime each!) into coasters. I did need to trim them a bit, but it was easy-peasy with a razor. I think reviewers who thought these were too thin must not have realized that these are not meant to be coasters by themselves.

Worked for what I needed.

I used these to make some coasters. I cut them to shape (easy because of how thin they are) and stuck them on the wood block to make coasters not stick to the bottoms of my glasses. Also prevented drips. I’m sure there are more applications as well
