I always feel safe when I'm carrying My Kitty! The Streetwise My Kitty Self-Defense Keychain is made of unbreakable lightweight ABS plastic - this plastic is as strong as metal! It is very easy to carry. You can attach it to your keys and it will fit right in your pocket or purse. Your fingers loop through the eye holes so that the tips of the ears can be used to defend yourself against an attacker. Measures: 3.25" x 2.25" and is less than a quarter inch thick. Covered under a one year warranty. Made in USA.
