Your BLINGSTING comes with a cute casing that securely holds your canister. If you use (fire off) your Blingsting, you should replace it. While there are about 10 shots (bursts) of pepper spray in each half ounce canister, the shelf-life would be diminished after one use.
You can order replacements online. Simply pull apart the pepper spray canister insert from the outer cover. Slide the new half ounce canister into the sleeve until you hear a ‘popping’ sound. That means it’s secure and all the way in.
