How much toothpaste do you use each time? People always squeeze excessive amount of toothpaste unconciously. This unique toothpaste is designed with a square mouth in a 'Just Right'size to squeeze 'Just Right' amount of toothpaste. Toothpaste squeezed out would be a thin layer to cover the toothbrush hairs. In this way, the waste of toothpaste is reduced before you even know it.
