NOSE CLIP CARE INSTRUCTIONS

Do not bend nose clips in half. As with all metal, repeated bending back and forth will lead to breakage. Nose clips should be gently contoured across the nose bridge if the wearer to provide a snug and secure fit. Use minimal adjustments as needed during future use, taking care not to over flex the nose clip as it could lead to breakage. Masks should be stored with nose clips in the same position as when in use.

Warm/Cold water wash — Keep water temperatures under 30 degrees Celsius.
Air dry and/or hang dry garments- tumble dry on low heat if absolutely necessary.
Do not Iron.
Avoid abrasive surfaces — Do not wash with items that may snag fabric (e.g. Velcro).
