What are the advantages and disadvantages of fish-shaped masks?

Fish-shaped masks have the advantages of large arched breathing space and good sealing, and are more comfortable to wear than traditional masks.

The key is that if you wear lipstick, you don't have to worry about sticking to the mask, not sticking to your nose and mouth, and the upper and lower packages are tight. The tone-on-tone black ear hook is elastic and will not pinch the ear at all.

Disadvantages: the face is too big to cover the nose, and the mask always runs to the chin.
