Toothpaste is one of the most commen daily necessities in our lives.
And due to the traditional round-opening design of the toothpaste, the contact area between toothpaste
and toothbrush is small, so that it’s easy to make a situation of the drop of toothpaste.
For this reason, the rectangle-opening toothpaste is
designed. The contact area between toothpaste and
toothbrush will be increace because of the small design.
Therefore, toothpaste is not going to dropon clothes.
It’s good for conservation of resources and convenient.
