This Seongsu showroom grew out of one simple belief: small things can make your life happier. Oh, Lolly Day has called itself “the brand that sells happiness” since 2014. It turned the old Happier Mart Seongsu, its former select shop, into this new flagship. Yellow shelves are packed with stationery, little goods, bags and the brand’s Monnanees characters, all in bright, punchy colors. Read the short notes tucked beside each item, and you’ll see the happiness this brand talks about lives in small, everyday things. On a day you need a little lift, why not drop by at the end of a walk in Seoul Forest? Focus Item — Diary & Calendar. Oh, Lolly Day’s take on keeping a record, filled in one small square a day. As the year turns, it’s often the first thing people reach for in the shop.
