I really wanted some caps with different colored fonts and these are awesome, before I buy them will they work with a poker II? Mine is currently in the mail
They will fit on the Poker, but consider this... it is important...
The stock keycaps on the Poker II are high quality thick PBT and will feel way better than any thin ABS caps. Those Taihao sets are thin ABS despite being doubleshot, and while they are decently made, they are thin and light and are not even in the same league as the stock Poker II caps, so you may well be disappointed with them.
I would recommend rather finding some really great keycaps that you like instead, like for instance the upcoming GMK HyperFuse set that Bunnylake will offer. It's not worth putting cheap caps on a board that already has high quality ones.
