I received a shipment in one of those bags, thought it was cute and unique. Now I use it for a tobacco pouch.

Wouldn't reuse it for anything else. Like shipping a small sample of herb to a friend... naw, But if I do ship herb, of course which I've never done and won't do... I'd put it in a hard side box, vacuum seal, twice, and ship. You have to wash your hands with alcohol prior to touching anything else. It's call asceptic technique. Learned it in a medical lab...

Use it for worry free shipments. But of course, no one ships herb....

yeah, right. Luck and Life.
