Items from estate clearance! I'm not sure what this is, but after some research, it seems to be a camera adapter? Maybe. Please look at the photos and if you know what it is, please let me know! Please judge the condition and size from the photos! It seems to be old and used, so please only purchase if you understand this! (Important Notes) Please be sure to read the following: ◎ Basically, only what is stated in the description has been confirmed, and I cannot be held responsible for anything else. ◎ We do not accept cancellations after purchase, so please make your purchase with careful consideration.
