Our cotton swab lip glaze contains cotton. It will not stick to the cup and will not fade. Its use is very simple: first put the cotton swab vertically, draw a horizontal line mark at one end, and the lip liquid will flow to the other end. Wait a few seconds, and when the other end is fully soaked with the lip liquid, it can be used. Finally, use the cotton swab to evenly fill the upper and lower lips. And it can be discarded after use.
