Koishiwara-yaki, Hayakawa Kamamoto, Western Liquor Cup Although it's called a cup, it resembles a small wine glass or goblet. It's about 8cm tall and has a beautiful layered color scheme. New and unused. There are small bumps on the rim of the cup, which feel slightly rough to the touch (see photo 8). There's also a small bump in the center of the cup, which I believe was made during the manufacturing process.
