This is a boat-shaped kogo (incense container). I believe it's a rare type of kogo. I think the material is ceramic, but I'm not certain. It comes with a box, but there is no writing on the box. It has been stored at home, so some aging is unavoidable, but the condition is generally good. Please check the photos and make your own judgment. Only those who understand and accept the condition are kindly requested to purchase. Size (approx.): Height: 3cm, Length: 7cm, Width: 3cm ❈Instant purchase is welcome.
