MicAuto Escape Tool, Emergency Escape Tool Keychain with Window Glass Breaker and Seatbelt Cutter for Car, Pack of 2 (Black)

Unlike most of these things, if you're persistent enough, it will break glass. Did not test the seatbelt cutter.

Bought to spare, the glass broke at a click, very useful, I hope never use it

I keep this on my keyring for emergencies- my old one broke and needed to replace- this not exactly like my old one but it'll work

I like this, you get two in a box. It does both cut the seatbelt and brake the window. Bought this for my son's keychain!

tres bien
