Review on 🔑 LSIKA Z Shields Training Keychain: Your Ultimate Emergency Defense Tool by Mark Greenwood

They are ideal for single use. They are small and fit anywhere. They can be hung on a purse or keychain. They are plastic with a one-way valve in the middle. There are straps on the side that can be hooked over the ears. Use once and discard. I keep one at home in my first aid kit and I carry one in my purse. I love her.
