So you go to get out of your car and walk into a store, but forgot your mask, so you turn around and walk back to your car and put it on. This wouldn't happen without a mask strap holder! Wicked bargain at $4.50. And I was told that college students aren't aloud to put their mask on a table, so this would be a great back to school gift or for younger kids, not to forget their masks at school. This is so much easier than searching for your mask, although, sometimes I forget it's around my neck.
