Fuchikashira and kozuka decorated with lobster (Ise Shrimp). Kozuka is signed "Yamanaka Mitsumasu" with Kao. He was active around 1825-1850 nad learned his craft from Iwama Nobuyoshi.
Both pieces made of shakudo with nanako ground. Lobster is inlaid and decorated with gold iroe.
This is not an original set, however kozuka and fuchikashira are very similar. I can sell them separately though.
Size:
Kozuka: 97 mm x 14 mm x 4 mm
Fuchi: 37 mm x 19 mm x 14 mm
Kashira: 33 mm x 17 mm x 12 mm
It comes without a kiri box. However I can make a custom one for additional $160.
