ZENZA Bronica Industry Extension Ring Set for close-up photography, A, B, C, and C set, for S, S2, and EC. This item was acquired from a person in their 60s. They took good care of it, and as they said, the exterior is generally clean. While generally clean, please consider that it is a used item, so there may be some minor scratches, small stains, and signs of use. I have confirmed its functionality, and I believe there are no particular problems. *If you are concerned about minor details, please refrain from bidding. Included items: Regarding shipping, I will wrap the item in bubble wrap and ship it in a cardboard box. Thank you. Management Number: 2000004586485 S/N: 205370 ok
