Disposable dust mask (head loop) Hi-Lac 1 box (10 pieces) 655-02 1 box (10 pieces)

The face contact surface has a high degree of adhesion and easily follows facial movements, so it fits snugly to the face. The tightening strings can be adjusted while wearing the mask, and it can be folded with its shape-restoring structure. The exhaust valve prevents stuffiness inside the mask caused by exhalation, making breathing easier. Since no metal parts are used, it can be incinerated. Uses a high-performance bipromicron filter.
