Set of 2 glasses, Bay Bridge. It's unclear if this is the manufacturer's name, but the words "Bay Bridge" are visible on the bottom. The drinking rim is round, but the glass tapers to a triangle shape at the bottom, which is lovely. When stacking, they fit together if you align the angles, but they may shift slightly. Diameter: Approximately 7.8cm Height: Approximately 8.0cm Weight: Approximately 240g Capacity: Approximately 230ml when full These are used items, so please consider this before purchasing. Payment via convenience store/ATM is also OK. In that case, please let me know your expected payment date. (20250520-24060750)
