Whispering cup / Messages printed paper cup

Whispering cup
Whispering cup

After using a disposable cup, many people casually throw them away anywhere.
This product’s design concept is to make people realize that they should do recycling after drinking with a disposable cup.
When people drink some tea or something to drink with a disposable cup, their eyes naturally get gazing at inside of the cup. The messages following the line show the people the other message. When they get into a final message, they will have to throw a paper cup into a recycling box because of the fact that it says,
“I can be recycled.” This whispering cup will lead you into a slight practice.
