Made from a clear silicone material, these stoppers won't slip and will easily match any color material.

For your mask wearing comfort, use these adjusters to tighten or loosen your elastic ear loops.

These cord adjusters are great to make masks fit just right behind the ears and are very comfortable. They are difficult to place with just your fingers. You need a loop turner or needle for easy threading. Loop turner sold separate.
