Thank you for finding this among many others. This is a rock glass called "Crumple Old" from a collaboration between Kimura Glass and Makoto Komatsu. It has been displayed on a shelf, so I would like to pass it on to someone. :) *In the first image, it looks like there are two glasses, but it's a shadow! *Please understand that this is a used item, although it has been disinfected. *The original box has been discarded. The box will be a recycled one. Please understand. This "wrinkle" glass, designed by Makoto Komatsu, is in collections at museums both in Japan and abroad, including the MoMA, Museum of Modern Art in New York. It has been a long-selling product for over 40 years since its release by Kimura Glass in 1980. It fits surprisingly well in the hands and mouths of everyone, men and women, right-handed or left-handed.
