Belle Vous Self-Adhesive Cork Coasters (50 Pack) - 9.5 x 9.5cm / 3.74 x 3.74 inches - Square Backing Sheets with Strong Adhesive - Mini Tiles/Mats for Wall Cork Board, Coasters, and DIY Craft Projects

Really delighted with these cork backings. I purchased to back my coasters that I paint pour on 10x10cm tiles. Don't be put off by what seems like a much more expensive item compared to other cork on here. Still works out to only 42 pence per cork tile. I've previously purchased other, less expensive cork backings that I've not been really happy with (too thin, just that bit too large so I needed to trim) and purchased these on the recommendations of the reviews. So thank you paint-pour artists! The cork is just chunky enough, they're a perfect fit, super sticky, and take an ink stamp really well. I'm a very happy customer.

I used some of these to level a bed. I live in an old house and the floors are very uneven. I stuck a few of these together to use as a little platform under the bed legs to make the bed perfectly level; with the top couple cut out to ensure the legs don't slide off.

Used these to back tiles which we decorated with acrylic paint. Finished them off very nicely. Easy to use.

Just great for using with the wood squares, the right size.

Nice and easy to use good adhesion

The coasters were better than I thought

I bought these as backing for tiles so that they could be used as coasters and they worked perfectly. They are the perfect size for a standard tile/coaster and are very easy to apply - just peel off the white cover and stick on.

Worked really well for making fabric coasters. The fabric sticks well and looks good
