Topre Realforce All keys have been confirmed to function without any key damage. The condition is as follows: * There are some areas with discoloration and scratches due to aging. * One of the parts on the back for adjusting the keyboard angle is missing (see photo). * Cleaning has been done as far as possible, but there are areas where dirt remains. * There is a connection defect on the left corner of the housing (it doesn't lift up unless you lift it with your finger; there is no problem in use). Although there are no problems with use, please consider this only if you understand the above.
