Up for buy it now are custom made Model F and Model M Buckling Spring Keychain/switch testers. Each lot is for ONE OF EACH KEYCHAIN SHOWN with RANDOM KEYCAPS. These will also fit any other Model M or Model F keycap if you want to change it yourself.

If changing the keycap, tilt the barrel all the way back while pressing the keycap back on and it should seat just fine. Feel free to message me if you need a video of how to do this.
