Moon got her degree in jewellery art, after being educated in Seoul and Pforzheim. Her work was on display in Korea, Japan, USA, Germany. The Museum of Arts&Design in New York purchased one of her artworks. Choonsun Moon works with cardboard paper, wood and plastic. The small elements are put in such an order that circles are completed to form a necklace, bracelet or brooch. It results in highly aesthetic pieces, made with great care. At the same time the pieces are playful and striking by their size and flexibility.
