What are the ears in the mask?

1. The inner ear is equipped with a mask, and the ear band surrounds inward, with 2mm wrapping bands at both ends.

2, the external ear wears a mask, and the ear band is surrounded outward (there is also a kind of wrapping band, but the ear band is wrapped first).

3. The difference between the inner ear band and the outer ear band is the direction of the ear band. According to the processing technology, the ear strap is directly spot-welded on the mask body (another ear strap is to wrap the ear strap first and then point the ear strap), and the surrounding direction of the ear strap is outward. The inner ear band is made by fusing the ear band to the body, the surrounding direction of the ear band is inward, and then wrapped with a 2mm packaging band.
