Soft metal Kabutomushi aka Japanese Rhinoceros Beetle menuki. I am sorry but I am not sure what they are made of. My best guess would be shakudo with parts that lost patina long time ago, and now the patina grows in the previously damaged areas. That is why colour on the surface is shiny black and red with many tones in between. Made in edo period.

Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
