just one thing to mention, i order two sets from a seller that only had black and white (1 x black & 1 x white)....
the black set i received had an issue with the printed buttons being faded or a different white to the others (not really a major issue, just would have bugged me)
luckily the seller is sending out another set....
if your ordering a batch of them, it might be something to mention to them or to expect


may not be that obvious in the pics, but the B and X are slightly washed out (most probably will fade of alot quicker than A and Y)
its more blatant in your hand...
they are cheap china replicas... so in a way you get what you pay for
