But the cup with handle also has problem of cleaning which is common failing of all cups. Incrustation sticking to the wall of cups is usually hard to clean by water. Double wall cup is a cup with rubber cup sleeve which has a handle. The rubber cup sleeve has a function of thermal insulation with a good visual effect. The sleeve can also be inserted into cup to clean the wall by special texture of itself. Stubborn dirt will be moved rapidly and thoroughly as long as you turn the inner cup sleeve.
