Review on 🍶 Premium Natural Cork Coasters by Hygloss Products: Protect Your Surfaces in Style by David Cook

They are a little flimsy on their own as others have pointed out. I used them for a DIY coaster project and with thick paper and a few layers of fancy bag they are much more durable. If you want to stick something on them to jazz them up, I highly recommend them. If not, maybe apply a layer or two of polyethylene or something to make them a little stiffer/stronger.
