It's often for people to drink beverage via straws; however, straws are made with PVC and PP plastics. These materials not only consume sources but also pollute the environment. Foldable Straw is composed of a straw and a straw sheath out of a paper, reducing both wastes and bulk volume.
When a straw is needed, the user press the paper gently to pop up the Foldable Straw, and press back gently again to flatten the straw to put away the straw along with its sheath into a recycle can.
