When most people use the toothpaste, they just use it without any consciousness regarding waste.
Even if they squeeze big amount of toothpaste, they just use it without any consideration.
Eventually, people just keep toothpaste in their mouth, and spill it later.
Also, most people just use a large amount of toothpaste. While they have some knowledge on toothbrush, they don’t know how to use with proper amount of toothpaste.
I want to give the solution to this problem to prevent people from wasting the toothpaste.
Making the hole for the entrance rectangle shape, not round shape, toothpaste could come out only little amount.
