This is a release button and hot shoe cover from Nanigashi. Release Button S [Hammered Finish] Bare Hot Shoe Cover [Hammered Finish] Bare Size / w18.3 x d18.0 x d3 mm This is a hammered finish hot shoe cover made by machining brass. The craftsman hammers each one individually, and the pattern that emerges when the light hits it is very beautiful. I am selling it because I no longer use it due to organizing my equipment. Purchased new in April of this year. There are no scratches and the condition is good. It is sold as a set. The 1st and 4th photos are reference photos.
