This is a Hyperglide mouse feet set that is no longer sold. I bought it a while ago but decided not to use it, so I'm putting it up for sale. The condition is that I have kept it carefully stored without opening it after purchase. I'm afraid I can't accept price reductions, as I'm selling it at a low price as much as possible. Thank you for your understanding. Instant purchase is OK. I don't smoke, and I don't have any pets. To prevent swapping, returns after purchase are not accepted, so please refrain from buying if you are concerned. Hyperglide Mouse Feet for Microsoft IE3.0/IE1.1 2set (MS-3) Brand: -
