Review on Premium Self-Adhesive Cork Squares: 110 PCS Cork Adhesive Sheets 4 x 4 Inch - Ideal for Coasters, DIY Crafts, and Cork Board - Mini Wall Cork Tiles Mat with Superior Strong Adhesive by John Pound

These are AWESOME tile coasters - just peel, stick and you're done! I got blank white 4x4 tiles from the hardware store to make resin coasters and they turned out amazing! They are very sticky and stick very well - in fact one was placed askew and when I tried to refold it to reposition it the cork started to fall off meaning you won't have a problem pulling them off, it is a permanent connection. It's ok as there's a ton here and a tile is about 19 cents. MUCH EASIER than trying to cut cork into 4x4 squares and glue them together (#Nightmare!)
