Well, if you use them, Dark Angel replaces what you use. So, that would make the price higher.
That's a cool feature.I haven't seen any other company offer that with first aid kits.
I know some body armor companies offer that.If your vest saves your life they get you a new one.
It has to be used to save someone's life though, they won't replace bandaids and stuff.But I guess most of their kits are mostly trauma stuff.
Still paying $170 for a little cube of silicone is crazy ...
