I was in a hurry when I bought my black on black Realforce 87U keyboard. I want to get rid of the black on black keys so bad I don't care what the replacement keycaps look like as long as the characters are readable and the Topre feel remains. Anyone know of vendors currently selling keycap sets for this keyboard? As a side note, I am completely baffled why in the world anyone wants black on black keys. Setting aside idiosyncratic reasons like personal aesthetics, is there some practical reason anyone buys them, perhaps CIA agents in deep cover that need to type secretly in public (lol)? I just don't get it. Thanks!
