Review on Silicone Non-Slip Coasters for Drinks: Set of 6 Perfect Soft Coffee Cup Bar 🍹 Coaster Holder for Tabletop Protection and Fit Any Size of Drinking Glasses on Any Table Type by Brandon Skeet

These coasters are wonderful. Nice and big, they don't slide on the surface, they don't leave marks on the wood, they are very flexible and easy to clean. Although they catch condensation from bottles, jars and glassware; If there is a lot of it, the bottom of the glass will still drip when you take it off the stand. But still better than other coasters. I would recommend them.
