A large chip was repaired with putty and lacquer, allowing it to be used as a teabowl. I hope you can appreciate it as an extension of the pottery shards. I've never seen anything quite like this before, so I believe it's undoubtedly a rare piece. The ultimate in minimalist tea ceremony aesthetics. I've used it to prepare tea many times, and I would be delighted if someone else would cherish it in the same way. By the way, it's said that if you encounter an old Shigaraki teabowl, you should treat it as if you've met your enemy, because old Shigaraki teabowls are known to be so rare. The bottom has a thread-cut finish, and there is a slight wobble.
