When you eat outside, drink tea, eat snacks, or fix your makeup, there are many times when you have trouble finding a place to put the removed mask! With this strap, you no longer need to "put" your mask somewhere. Simply hook the hooks on both ends of the soft patterned tape to the ear hooks of the mask. It's a great item that people who have used it say, "It's so convenient!" It's a set of 3, so you can share this convenience with someone.
