Review on 🧵 60-Pack 4-Inch Self-Adhesive Cork Rounds - Mini Cork Tiles Sheets for DIY Crafts, Coasters, and Wall Decor (0.08-Inch Thickness) by Kristen Simpson

They're thin, but usually what you're looking for when they are comes down to things like attaching to the bottom of coasters. We are prepared for this because we 3D print many coasters here. This and other office-related items (pen holders, etc.). So far they seem to be holding up and offer just enough coverage and the protection you would expect. The sticky side seems to hold too. We thought about it when we came across options that started peeling off within a few days. So far we have not encountered this. However, we will update if we find otherwise. It's also a fair amount of coaster for the price.
