I would be VERY INTERESTED in a set of double shot key caps as long as their PBT. im rocking a K70 (not rgb because can't find a mx blue rgb k70 anywhere :( ). the stock keycaps are ABS and i hate how slippery (smooth) they are. My friend just got his Ducky shine 5 the other day and the keycaps that came with it are double shot PBT and they feel amazing. they're thicker but main thing is that they have a matte (grain) feel to them that just feel perfect.
i was looking online for a keycap set but came to find out that the bottom row is not standard :(
i would be willing to pay $40- $50 shipped if they're PBT.
