Generally, when a lipstick is used up, there is still 1/4 of the whole section left, which is difficult to take out.It's a pity to throw it away. It can only be used by a lip brush or finger, which is inconvenient and unsanitary.
The lipstick shell I designed can reduce the waste by 1/2.
The lipstick's outer casing and the small tube carrying lipstick are both divided into two parts, one is linked by a magnet, another is linked by a pull ring.When conventionally part is used up, you can remove the detachable part, and the remaining lipstick can still be used.
