This set of coasters is both attractive and functional. I love the case they come in because they are always together when I need them. Furthermore, the bamboo is sufficiently thick so there are never any water stains on the furniture. It is a well designed item which has become an essential part of my bar equipment but I also think I shall buy some more sets for holiday gifts. On top of all that, the coasters are made of bamboo which is of course "green" and an environmentally sound product.
