Pepper Spray key ring

The problem with carrying things like this Pepper Spray keyring from Bigwing around with me is that I spend the whole time primed and ready to attack at the vaguest whiff of trouble, which will no doubt end in blind stinging tears one day when I squirt some hapless chap seeking directions right in the eyes. Luckily, this spray causes no lasting harm, and can be used 8 times, so there's plenty of margin for trigger happy error.
