DENG is a contemporary tea set designed by DE+ for its client Pertouch, a leading brand of urban portable tea utensils. Pertouch has been committed to explore the boundary of modern tea utensils, and DENG is its first attempt in tea sharing experience for urban life. The whole tea set includes a teapot, a slippery net, a water barrier, and three teacups. The design is portable and space saving. The Russian-doll structure allows multiple components transforming into one piece.
