These are thin glass cups from the Meiji to early Showa era that were found in my deceased grandfather's storehouse. The bubbles are lovely, but please refrain from purchasing if you dislike them. They are dull, but I wiped one to test it, and it revealed a clear brownish-gray color (see image 4). All are unused, but they are very old, so I will wash them before shipping. Please let me know in the comments if you don't need them. Height: 10.5cm Diameter: Top 6.5cm, Bottom 4.5cm
