Thank you for viewing. Instant purchase is welcome. This is a lens pouch made by Kyocera CONTAX. Judging by the size, I think it's for the G series lenses, but I don't remember exactly. The size is: Height: 79mm Width when flattened: approx. 100mm Diameter: approx. 60mm Although it's unused, it has been stored for a long time. There is no stickiness or cracking, and it's supple. Thank you.
