If there are powder brushes, blush brushes, foundation brushes, eye brushes, lip brushes etc in the makeup brush set, all other brushes have the same quality standard, that is: no lose bristles, no marks on ferrule and handle, the handle and ferrule should be smooth and straight etc. It is easy to check the quality, and will cost less time.
While for lip brushes, it is different, besides the above quality concerns, you should pay attention to the following possible problems:
1. If the bristle top is pointed, according to the working instruction of lip brushes, each lip brush bristle should be pointed, if not, the lip brush is not qualified;
2. If the brush head is protected with a tube; as lip brush is pointed, which may be out of shape during shipment, so lip brush head should have a protective tube.
3. If any bristles are backward by the tube. since each lip brush should have a tube covered around the bristles, it requires a lot on the techniques and is easy to have backward bristles, while backward bristles are not qualified.
4. If the lip brush is retractable, ensure the retractable mechanism works well and have enough life time for daily use.
