Originally a 91-key keycap set, 16 1U keys are missing because they were used for a gadget. Everything is shown in images 1 and 2. The keycaps for sale (in the images) have never been used and appear to be in perfect condition, but the price has been reduced because the corner of the plastic case is cracked (from the beginning). There is no printing on the keycaps, and they are all the same height. Would these be suitable for a keyboard with a small number of keys?
