pok3dYou can pretty safely assume that a generic 60% or greater keycap set will fit an ANSI Pok3r, as it's the most common 60% configuration of the most commonly offered layout. I personally doubt these are produced by Tai-Hao, as most of their other sets on Massdrop openly state the manufacturer, but then again who knows. My guess would be that these are clones of other cherry clones manufactured in China (i.e. something like IMSTO clones, which are said to be just as good or exactly the same), based on the low price and lack of branding but maybe one of the drop organizers can give you more reliable details. Cheers.
pok3dI do not think so as these are listed as "Cherry Profile" while Tai-Hao keycaps are a modified variant of the "OEM Profile". It would be nice to know who manufactures these though.
