These Lanyards are so great! I wish I would have gotten these sooner! They are amazing! These lanyards work so great for clipping to your mask so you don't have to constantly touch it. It allows you to let your mask hang around your neck while you are not wearing it. It also allows you to not use the ears straps on the mask. The lanyards can be used for glasses as well. The clips work very well and are easy to use.
