The production batch number of MAC: Take A9 1 as an example, where A stands for the production line, 9 stands for the factory month in September, 1 stands for the year of 201,and A9 1 is 201. The color number of MAC is the Chinese and English words at the top of the outer packaging carton or at the bottom of lipstick, such as morange, instead of A9 1 alphanumeric.

Usage: first make the lip bottom, then make the lip bottom with lip balm, and then apply lipstick, which will be particularly colorful and lasting!
