it's cheaper to go to stationary store
3000won(about $3) for a dozen vs 5600won(1600 for dozen + 4000 shipping to my house) from that site, plus I can't buy from that website cuz I need Korean citizenship number to register and I dont have that.
if it doesn't matter, Monami or Dong-A
I'll get a dozen
I'll look around and see if other stores carry Dong-A
