Reusable, washable and adjustable, this non-medical face mask is a great way for you to take protection into your own hands. When worn correctly and used in addition to other preventative measures, reusable masks can be a great way to help safeguard yourself, surfaces and others from harmful particles. These cloth masks have a bendable nose wire and adjustable ear bands so you can adapt the face-covering fit to be secure and non-gaping. Easy to hand-wash and hang dry, this mask is a more cost-effective and environmentally friendly alternative to disposable masks. The included silicone rubber extender is designed with a series of notches at each end that help hold the mask's ear loops in place. Simply slip the ear loops over the notches on each side then wrap the flexible extender around the back of the head to keep your protective face covering securely in place. For added comfort it is made from a silicone rubber that won't pull at your hair. To make sure you've got a good fit, the ear loops can be adjusted on the extender by moving them from notch to notch until you find a fit that's right for you. Black mask is made of 100% cotton material with a rayon liner. Kit includes: (1) extender strap and (5) PM 2.5 mask filters.
