These coasters are so pretty; we were really excited to use them. However, we've only had the coasters a couple months, and we've noticed that the wood 1) leaks condensation onto our kitchen table through the wood in the coasters and 2) the condensation sticks to the glass that's sitting on the coaster, in a sense gluing the glass to the coaster. We wanted coasters that at the very least didn't leak condensation everywhere, and these did not do that.
