It has a silver-like luster, different from ordinary copper incense burners, so I picked it up on a hunch. Upon closer inspection, I saw "祝銀婚" (Shukugin Kon - celebrating silver wedding anniversary) on the back, and it made sense. This is a work by Kiyotomi, a metalworker. As it was made for a silver wedding anniversary, it is highly likely to be a "silver product" containing silver. The interior also has a feel unique to silver. First come, first served! Please judge it based on its beautiful and subdued luster. This is a masterpiece that has gained character with age. It is in good condition with no noticeable damage. Approximately 13cm wide, 10cm high, 5.9cm opening diameter.
