Stretch mask 300 pieces FV-R 1 case (30 pieces x 10 small boxes)

We use filter material that has excellent collection efficiency and low intake resistance. Compliant with JIS T9001 general-use mask standards Since no metals are used, the effort of separating waste can be reduced. The space keeper in the center of the mask creates space and reduces the feeling of pressure on the face. The ultra-fine fiber filter and thick pre-filter effectively capture large and small particles.
