We are living in multi cultural society, where people prefer to do things differently. The Duo Cup is a travel cup that inspired from Chinese traditional tea cup design. Duo cup allows for two ways of drinking beverage; it can be used as a regular cup, or it can be used with a straw. It is designed into two separate cups and that users can use them separately or as a combined duo cup. Users can drink liquid like a normal cup without trying to open the cap, yet the design can be spill proof. Such making DUO CUP ideal for those on the road. The beverage can be filled into the cup from either end. This concept challenges how people views the function and limitation of a cup.
