OMRON small inhalation mask, 1 piece, with rubber band for convenience. This is a set of OMRON inhalation masks. I have stored it at home after purchase. Although it is new, I'm not sure if it was like this from the beginning, but upon inspection, the mask part is generally cloudy. Please consider if you are not overly concerned about this. - Model number: NE-U10-2P - Product name: Inhalation mask (small) - Contents: 1 piece - Brand: OMRON - Accessories: With rubber band Thank you for viewing.
