Made of stretchy nylon. Super comfy.
The length of the precut elastic with built-in buckle is approximately 8.5 inches (4.25 inches folded in half), but it stretch up to 9".
See photo on child size mask and adult mask for reference.
Not recommended for children under 2 as the adjustable disc could come off and present a choking hazard.
Price is per set
2 Colors that I picked were out of stock #47 and #48 so those will be the mystery colors. As soon as I can confirm the colors they will be updated.
