KITOWA Porcelain Diffusers are a great addition to any fragrance collection, and also makes for a wonderful gift. Nicely packaged, each box comes with a Diffuser Refill and a Porcelain Diffuser made from 'Aritaware'. Established more than 400 years ago in the early Edo period, Arita porcelain is the origin of Japanese ceramics. Sturdy and beautiful, this black base is a bold statement piece. To use the diffuser, simply pour the fragrance into the container, place the top cover, and insert the porcelain stick. The diffuser spreads the scent thanks to these ceramic sticks made from a new material. This revolutionary material is created from a new manufacturing technique that does not exist elsewhere.
