These vinyl snap straps are perfect for holding the elastic on your mask around the back of your head and off your ears! 3 snap positions so they can easily be adapted for all size masks. At least 8″ of elastic length is required on each side of the mask for use (for adult sizes) and 7″ for children’s masks.
Finished flat size when cut at 1/8″ is 6-1/8″ x 1-1/8″. When snapped on the first snap, the ring is 6″, second snap measures 5-1/4″ and third measures 4-3/4″
