Two keycap-cannibalized Access keyboards:
The coloured keycaps are engraved/infilled, most of the other ones are doubleshot.
The arrow keys on the upper keyboard are not original, but lasered Cherry keycaps instead.
Would sell for 20€ each or 35€ both + shipping (note they are heavy: upper one ~1,2 kg, lower one ~2,1 kg).
I must confess I don't really know if they work (since I never tried), but I'm confident they do. Of course I offer refund if they don't, but perhaps you should wait for other offers
And what about a Tipro instead? I have several with quite similar layouts (except for a touchpad).
