Description

Liquid pen

The invention relates to a liquid pen, in particular to a liquid pen which is quantitatively discharged and has an inverted leakproof function.

There are many kinds of liquid pen types that are commonly used at present. For cosmetics, for example, the commonly used cosmetics are nothing more than liquid and solid. Because solid cosmetics can be easily broken if they are made into strips in the shape of a pen, therefore, makeup It is usually preferred to add liquid cosmetics to the pen.
