The feet from a Logitech K270 keyboard are likely compatible with other models (K260/275/200/MK270/260, etc.). (Please confirm compatibility before purchasing.) However, please note that even with the same model number, there may be model changes. (They may not work with models that have the "logi" logo.) This item will be sent via anonymous shipping (free shipping). It will be shipped via Nekopos or Yu-packet Post (mini). I may be slow to respond due to travel or work. Also, I may not be able to ship on weekends, holidays, Golden Week, year-end/New Year holidays, or Obon. Please be aware of this if you need the item urgently. Thank you. (Management number 3)
