The built-in KN95 nose clip is beautiful in appearance and easy to use. The mask is made of high-quality non-woven breathable fabric. The high-quality melt-blown cloth has a stronger filtering effect and effectively blocks the invasion of external dust and bacteria.
The KN95 built-in masks can be used in various places in life, especially when traveling through crowded airport buses to pick up parking lots and busy city streets, kn95 masks play a perfect role.
