Bests & Worsts Reviews from Amazon

So disappointed. The good - The appearance, and construction of the coasters is excellent, I have had several people comment on how nice these look. The not so good - They are molding! I have not had them all that long, and we are just getting to the warm season where my glass may sweat, but at least three have now begun to mold, one day a couple of spots, a day or so later a large number of spots that are large colonies. Cleaning the coaster at first sight makes me feel better but the bamboo is stained permanently.
