When in Hannam-dong or Itaewon area, be sure to drop by the flagship store of Seoul-based design studio MMMG or Millimeter Milligram. They have a lovely range of notebooks, journals, calendars, wallets, mugs, and other practical accessories for the workplace and home. I really, really, really love their stuff because they’re well-designed.
Also on the third floor of the building that houses MMMG is an independent distributor and bookstore called Post Poetics. They sell super cool books on art, design and photography, and even harder-to-find international books and magazines. The best part is most of them aren’t sealed so you can take a peak or look through the pages. I’m pretty sure you’ll find no shortage of inspiration in the collections on display!
