Which is mine / paper cup

At the party, when we need to drink water, we usually use paper cup to drink. The paper cup all look the same, so if there are several people in a party using the same kind of paper cup, it is impossible to tell which paper cup belongs to whom. “Which is Mine” takes the guesswork out of which paper cup belongs to whom at party. When we get our own paper cups and scratch off the top layer, the color electronic digital fonts that covered by the scratch silver will be exposed. We can make number, letter or symbol which is different from others. This enables you to easily identify your own paper cup.
