Well, how cool is that !! Very interested in a review !!
If you only need 1 day's supply, try a 3.7ml bottle of breath drops:
You have to rinse it pretty thoroughly (pull the top off with pliers and soak the bottle and top in water for a day or so), but it fits really nicely in the little mini-pocket in my right jeans pocket.
Hahaha, yeah this dropper looks very promising. I ordered one when I found them and will post more details when it arrives.
It is 5.5" long so it's a bit shorter than your average bottle of pepper spray but that doesn't concern me. I'm always worried about the little plastic bottle of juice in my pocket leaking or exploding so I'd definitely be willing do deal with the size. As of now I'm reaching into my pocket about every 10 minutes to make sure my plastic dropper hasn't leaked.
The dropper top is the only thing that looks iffy. It has a stainless steel dropper top, but it was designed to hold eye drops so I think it'll work fine. The viscosity of our liquids may be the only issue.
