I'm a type 1 diabetic, so I used test strip bottles for my green. They're waterproof, air tight, and inconspicuous in my regular diabetes medicine bag. I used a meter case to keep it all together. It has 2 places for the green bottles with straps to keep them there, a mesh pocket for small pieces, clips, a small pipe, papers and other shit. And a center strap for a lighter (well, on the one with the red pipe). Thats some MacGyver shit.
i keep my stuff either in my backpack (love swiss army knife) if i'm on the go, or in my protein powder jar inside a ziplock bag. simple
