Review on Premium Large Drink Coasters: Moisture Absorption and Table Protection - Set of 6 Modern Black Rubber Coasters with Non-Slip Bottom for Drinking Glasses by Richard Puckett

These coasters fit but do not absorb moisture as stated in the description. For hot drinks so far ok. Anything left with ice for a while turns into a coaster full of water. The feathers keep the bottom of the glass or cup dry at first, but over time the bottom gets wet. Another problem is that if liquid collects in the stand you have to be careful not to bend the stand as it is flexible or you will spill the liquid before you can pour it out. So it's fine if you don't use it for iced drinks that will sit on the stand for a while.
