I hear you on the scratches on the keys and will work on getting replacements on ones that are prominent enough.
The truth is that I do not have extras to send out because GMK did not give me any.
That said, please PM me photos of your defected keys, and I will communicate with GMK and see if we can get some extras to replace them.
I can promise to do my best to help, and will have to communicate and figure out our options, so please work with me on this by sending me photos via PM.
