Hi, I'm new to this forum and group-buys (registered minutes ago in fact), so apologies if I'm missing something obvious and wasting your time. I'm very interested in one of those US Black keycap sets, but I'm not sure if I'm too late to the party or not. Is it only these extras that are still available (I take it 1800 keycaps aren't compatible with normal keyboards/MX switches), or would it be possible for me to still order an US Black keycap set?
