Qunclay 200 Pcs Cork Coaster Backing Self Adhesive Cork Squares Bulk 4 x 4 Inches Board Sticky Tiles Sheets Mat for DIY Crafts Supplies

Second time I purchased these works great on epoxy coasters

Great value for the amount I paid. Very sticky, works great on the back of a 4 x 4 tile. I approve this purchase.

Works great and sticks like a champ to ceramic tiles!

Easier to apply than the ones you cut to size.

These are a better solution than the little black circles on the bottom of coasters 👍

We ordered these because the ones that we normally get were out of stock. These arrived today, and now I see why they were a few dollars cheaper. They're less than half the thickness of the ones we usually get. Very disappointing, but they should do the job.

These are SUPER thin, not the thickness advertised. They are half the thickness posted in the description

These are much thinner than listed.
