I love love love stationary stores!! And Alpha is a large chain of stores here in Seoul, I see them everywhere. There’s even a store right down the street from me.
However, the best location I’ve seen is located in Namdaemun. There are 4 floors of stationary, craft, art supplies and more! You can spend some serious time here browsing. It’s the best!
Seoul, Jung-gu, Namdaemunno 4(sa)-ga, 20-42.
(Take the subway to Hoehyeon and use exit #5)
Here are a few photos of just a few of the areas. You have to check out this store when you’re in Namdaemun!
