Benco Dental ™ Mask Extender Straps completely eliminate ear pressure and discomfort by hooking the earloop mask onto the premium mask extenders instead of directly onto you ears. Made from food grade silicone, these extenders will protect your ears and prevent any chafing or pulling that normally occurs during prolonged mask-wearing. The Mask Extender straps features 3 convenient buckles on each side for fast length and pressure adjustment. Benco Dental ™ Mask Extender Straps are hypoallergenic and latex free and can be washed and sanitized for reuse.
