It's already pretty tough to find English keycaps that are nicely back lit like the Ducky's stock ones that only let light shine through the legend. That being said, hopefully if you do ever find one with Korean please let me know asap.
I don't think my dad wants a Leopold, price isn't that much of an issue for him (he's a hardcore audiophile and runs a business selling high end amps and home sound system equipment). So yeah, perhaps a Filco Majestouch that I can swap out with some nice keys for him. Anyways, let me know, thanks in advance!
