sorry yeah i mean that exact keyboard, the all white colour and the hangul caps. im looking for that - but cant seem to find it anywhereeee at all
The Hangul variants are sold exclusively in the Asian market AFAIK, so it'll be a good bit harder & more expensive to get them in the US but not impossible. Honestly though at the price you'll pay for that exact board, I'd personally just get a white one with the regular caps then get an aftermarket keycap set that has the hangul sub legends.
This thread touches on doing just that.
It looks like it needs two 2.25 unit shifts, so
those sets I linked in your previous post about Hangul caps
should work if you order one of the base sets, one modifier set and two of the modifier pro sets (in order to use the Taeguk symbol to replace the two 1 unit Windows keys. Reading suggest that the stabilizer mounts would have to be modified to fit the spacebar on the Leopold. Otherwise,
that matcha set looks to come with an extra 2.25 unit shift with an image on it instead of the "shift" text, a 1 unit Windows key and an extra 1 unit key with another image on it, which could all be used to fit without ordering extra caps, although it would not be symmetrical.
Anybody that's actually owned a FC660M and has actually swapped the caps before would know more though.
