I believe this is a tea waste water container (chagoboshi) used in the tea ceremony, but I'm not familiar with tea ceremony practices, so I don't know the details. This item has been stored at home, so please purchase it only if you understand this. I will wrap it in bubble wrap and pack it securely, and ship it as a fragile item. ・Diameter: Approximately 10cm ・Height: Approximately 11cm #teaceremony #chagoboshi #kensui #teaware #antique #retro #antique #teaceremonyutensils #chaji #pottery #yukoboshi #teaincenseburner #incenseburner
