Set of 6 rock glasses for Japanese sake with a simple design. They are called "tsuzumi-gata" (drum-shaped) and feature the manufacturer's logo. The design is very easy to hold. Sizes are shown in the photos. Each glass holds a generous 120ml, more than a typical ochoko (sake cup). These have been stored for a long time but are unused. I will wipe them down quickly with a disinfectant wipe. The box is a little dirty.
