Resealable Zipper bags
Especially when young folks going on outings into nature, they often carry a hookah with them as equipment. Such a hookah aready needs much space. Now, hookah tobacco is mostly available in huge and awkwardly shaped bins. To avoid carrying one or several (depending on everybodys taste) tobacco bins around, zipper bags are appropriate to portion the tobacco.
The special zips are tight and save - so our resealable zipper bags are a real relief for transporting portionable material.
