Hello,sir/lady

I am just wondering if i use Foreign credit card, will i pay in(do your store accept) US dollars or Korean currency directly?and if i use paypal, will i pay in US dollars (do your paypal account accept) or Korean currency directly？ I am just worried about the extra hand fee from bank so i want to ask you. I will be glad if i could pay in US dollars directly.

Kind regards
