For anyone wanting these keycaps but needing keys for compact layouts, the IDOBAO Gradient Shine-Through PBT Keycap Set looks to be the same set but with a bunch of extra keys (including smaller alt, ctrl, shift, etc). It's currently in pre-order, and also cheaper than this set.
Is there any possibility of a 1u windows key and FN key being made? I swapped out the keycaps on my corsair keyboard and it looks amazing, with just the windows and FN Keys not being replaced
