Purchased in 2019 at a solo exhibition by Shinichi Moriguchi at Fukumitsuya in Yurakucho (now closed). Originally purchased for 33,000 yen (tax included). I've been using it regularly, and it's developing a nice patina. I have too many trays and can't use them all, so I'm offering this Katani Bon to someone who appreciates them. Please check the size in the photos. Thank you.
