Shortening bottle / Cosmetic container

"Shortening bottle" is a cosmetic container which you can see how much cosmetics you are using and how much is left. This bottle shrinks as you use the contained cosmetics like pencils. Now that this bottle doesn't have to be transparent for the leftovers to be seen from the outside, it prevents cosmetic from exposed to ultraviolet rays. You can verify the amount left easily with only a quick glance.
When only small amount is left, with its small volume, it is easy to carry around. Also when disposing it, you can minimize the size of the waste.
