These are Ryukyu glass cups that were sold at the select shop CPCM in Harajuku. The handmade feel of Ryukyu glass, with its thickness and bubbles, has a nice charm. They are simple, so they are easy to coordinate with other dishes. I used them for drinking shochu, plum wine, and water. There is some clouding and minor scratches on the glass, but there are no problems with use. Please understand that these are used items. I will sell them as a set of two.
