Concept of "uninterfering design"
Whether it is reading a book or enjoying a conversation, the act of drinking always accompanies another precious experience. Items which do not obstruct that experience was the basis for this drinkware series. The angle of handles places no stress on the hand, as gravity and point of force applied is carefully considered. The brim of the cups slightly spans outward, allowing drinks to be smoothly poured into your mouth. Every detail is for the precious moments of the user－this is the fundamental quality of CAST.
