This is a cup from Kobo Jikaku. I was using them as a pair, but I broke one, and since then I've been worried about breaking the other, so I haven't been using it much. I'm selling it now because I'm organizing my tableware as I move. Please understand that this is a used item and has been stored personally before purchasing. I plan to list many other items, including Yachimun pottery, folk crafts, and tableware.
