Blentid is a perfume workshop in Seoul where customers make a personal fragrance. It is located near Seoul National University Station, on the third floor of a building on Haengun 1-gil in Gwanak-gu. Customers smell ingredients such as citrus, floral and musk, then adjust the ratio of fragrance materials to make their own perfume. They test preferred scents, consult with a perfumer and keep revising the fragrance, and the range of materials makes the process easy to follow for beginners.
