All items are used and show signs of wear. Due to the large quantity, they have not been cleaned, so please clean them yourself. Some items do not have receivers. (Please prepare a receiver separately.) To keep the price down, I will pack them roughly in a plastic bag and then in a cardboard box for shipping, without individual packaging. The breakdown is as follows: Logi performanceMX Gray (no unifying receiver, sensor damaged) Logi MX Anywhere 2 Gray (with unifying receiver) Logi MX Master 2S Gray x 2 (no unifying receiver x 2, Bluetooth compatible, one has no rubber grip on the vertical scroll wheel) Logitech M705 Gray (with unifying receiver) Logi M570 Gray (with unifying receiver) Logi M221 Gray (no unifying receiver) Logi M546 Black (with unifying receiver) Logi M705 Gray x 3 (with unifying receiver x 2, no receiver x 1) Logi M-RU77 Green (with receiver) Logitech M235n Gray (with unifying receiver) Elecom EX-G M-XGM10DB White (with receiver) Elecom EX-G M-XGL10BB Black (no receiver, Bluetooth compatible) Elecom EX-G M-XGL10DB Black (no receiver) Elecom M-LS16DL Red (with receiver) Elecom TK-FDM063 Black (no receiver) Elecom M-D4URBU Blue (with receiver) Buffalo BSMBW510M White (with receiver) Buffalo premium fit BSMBW500M White (with receiver) Kingston slimblade trackball mouse 72281 Silver (Bluetooth compatible) Eastern Times D-09 Brown (with receiver) Sanwa Supply MA-NANOLS7GD Gold (with receiver) DELL MS3320Wp Black (with Dell Universal receiver) Total: 25 units (apologies if there are any counting errors)
