Qincling 80 Pack Self-Adhesive Cork Coasters Round - 3.5IN Circle Cork Backing Sheets Mats Mini Wall Cork Tiles Coasters and DIY Crafts Supplies

While I wish these were a true 3.5 inch so they would fit my acrylic circles exactly, I do appreciate that the true measurement is listed in the description. The adhesion seems fine and it worked well for a cork backed coaster.

I stuck these to some wood coasters I painted. Press down nice and firm when you're sticking the cork adhesive side on and it stays on really well. More likely to tear the cork than you are to peel off the adhesive once they're on.

I 3d printed some coasters, and these are a perfect fit, easy to apply, and they hold well while making the coaster less likely to slide on any surface.

I use these for my resin coasters and they are easy to use and trim to any shape and size.

These are much better quality than similar items I’ve ordered in the past. They feel nice and sturdy and are thicker than expected for the price. I’m using them on the backs of wood burned coasters.
