When people using a staw,
they tie the packaging on it to decrease the amount of trash .
We combine the packaing and the straw, and make it looks like
the straw "fasten" a belt .
People can tear from the above and the under of the packaging without tied on straw ,
and decrease the amount of trash as they used do.
