Look at printing. 3M masks are all laser printed, and the printed marks are at an oblique angle of 45 degrees, while fakes are printed with ink, and there are often traces of uneven ink. Specifically, the real 3M mask is laser etched into stripes, and the fake mask is printed into dots. In addition, the serial number of the genuine mask surface is the same as 10 on the packaging box, while the serial number of the fake mask is printed and cannot correspond to the serial number of the packaging box.

Non-domestic masks, as long as they come in regularly, must have LA certification. Domestic masks, whether used domestically or exported, must be certified by QS and Los Angeles.

Putting it directly on the bag head may cause secondary pollution!
