Up for buy it now is a custom made Model F Buckling Spring Keychain/switch tester so that you can always carry around that clicky goodness.  Each lot is for ONE KEYCHAIN SHOWN with a RANDOM KEYCAP.  This 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.

USA Shipping will be FREE.  International shipping will be calculated based on location. Thanks for looking and please ask any questions that you may have!
