It makes perfect scents. Infused with a fresh green floral note, Soohyang's Itaewon 565 is the brand's signature bestselling scent, and is named after the address of Soohyang's first store. The Itaewon 565 Diffuser is ideal for scenting small spaces over a period of several months. Once the fragrance evaporates completely, the bottle can then be refilled with the same scent. Soohyang tip: recommended for new houses, newlywed houses and new stores — in fact it's said there is no newlywed house in Korea without a Soohyang diffuser.
