When we use disposable paper cups, especially in some special occasions, we often faced with some problems, such as while having a meeting in conference room, once we walk away and come back after a short time, it is difficult to identify which is my cup, for all the cups are just the same.
This scratch paper cup is just like scratch cards, we can use coins, keys or even nails, scraped off our names or some simple graphics on the cup, so it can easily distinguished with other cups.
