I bought these for friends and family to put in their backpacks, purses, brief cases to be used in an emergency. If they need to blocked a door from an active shooter, they have it on them and can put it under the door if it can't be locked and help keep the intruder out of the room. This is a great investment to help protect your family when you can't be there for them.
