These are cool cups – we love the colours, the size and the style. They are sturdy as well as cool. The fact they are made of bamboo is a great conversation starter and we love the fact that they won't be clogging up the landfill. We'll be sad when their life is over but will probably get another set. On the down side, I was dismayed to find these exact cups retailing at Stevens for almost $10 less than here on Mighty Ape.
