I recently acquired it from another user on Deskthority thinking I will be fine without numpad and I was wrong. For the purpose of mobile compact keyboard I have HHKB.
I would like to trade it for a fullsize uniform weight Realforce keyboard. Must be the black on black model, any weight will do.
I may also consider Fullsize filco or similar board with PBT keycaps with MX reds.

I'm keeping HHKB caps visible on picture. It will come with the standard caps.
