Review on 12-Pack Extra Thick Wooden Drink Coasters with Cork Edges - 4 inch Diameter and 2/5 inch Thickness for Hot & Cold Drinks - Absorbent and Reusable Saucers by Oscar Ferrell

I've recently gotten into laser engraving and have bought a few 'other' coasters that can be found online to test out. They were fine, but if you want honest, premium cork coasters that are VERY easy to use, give away and sell then THESE are the ones you need. Most cork coasters I've found fall into the "disposable" category, but at almost half an inch thick, they last a long time. I will buy again.
