Minima Glass is the most cleverly designed water glass I’ve ever seen (and had). The small whimsical dimple prevents the glasses from getting stuck together. Designed by Cecilie Manz for Holmegaard, it’s available in a set of 6 pieces (in three colors), or sold by piece (just in turquoise).
Price: $28.00 each or $180.00 for a set of 6

These glasses are beautiful, but the only place I’ve seen them was at Frank’s Restaurant in the Art Gallery of Ontario. Surely a commercial establishment would not buy water glasses at $28.00 each, would they? Seems extreme.
