haha,, Look so fun in Korea. I think they might understand what you are talking about, but you should know they're not really good at speaking in English..
Don't forget this,,, you don't need to say a sentence, because they hardly understand. you might say a WORD, like as " Filco, Ninja, tenkeyless, brown switch." I'm sure they know what you want exactly. Anyway I wish be there. Yes I'm Korean, but live in NZ.
