This is a set of 7 USB (female) to PS/2 (male) adapter converters. Six are from ELECOM, and I don't remember where the other one (purple) is from. They have been stored for a long time. As shown in the second image, there are no broken tabs. They should work without any problems, but since I don't have an environment to test them, please refrain from purchasing if you are concerned. I am selling these as part of my end-of-life preparations, so I sincerely apologize, but please understand that they are non-refundable and cannot be returned. Thank you for your understanding. #kuronekokurota's listings
