NO DROP LEFT / a new toothpaste package

NO DROP LEFT
NO DROP LEFT

How to squeeze out the last bit of toothpaste? Is a headache for many people.
We started from how to squeeze out the last bit of toothpaste, and improved the traditional form. Rethinking the export of toothpaste. Rounded rectangles are used at the exit section instead of circles to optimize the direction of the force when squeezing the toothpaste, so that the toothpaste no longer stays in the tapered space at the top, and can be squeezed out smoothly, effectively improving the experience when brushing, reducing unnecessary waste.
