Gjinxi 20 Self-Adhesive Cork Coaster Backing Sheets - Sticky Round Cork Sticker Peel Padding Ceramic Backing Sheets Pads - Fit Wall Mat Tiles DIY Glass

These work great on the back of my Resin coasters I make. They seem to be holding without any issues.

I needed something for the bottom of the coasters I was making. These worked out perfect!

I've been making diamond art coasters as gifts for several people over the last year. The kits came with the cork backing when I first started making them. The last couple kits don't, so I'm glad to be able to purchase these. Price was reasonable and they do the job as expected.

Don’t scratch our wooden table at all!

These are a little less than 1mm thick. For my coasters it's fine. Tested the glue with my finger and wasn't impressed. I'll either use a better glue, or replace them as needed. I think I'll just replace them as they could get pretty grungey and I wouldn't want to get "stuck" 😉 with scraps left by the better glue.

I got these and the bag was chewed through most likely a mice, 3 of the coasters were chewed so I had to cut it off to even the circle. I could have sent it back for that reason but I needed them to complete an order. Please be aware of stuff like that before shipping the item.

These are smaller than most round coasters. But they stick well and easy to use.
