Store a whopping pound (500 grams) of dry herb for up to a year with the 10.0L TightVac, also known as the Breadvac container. Made of tough plastic that lasts a decade when maintained and cared for, the Breadvac comes in 3 styles for every preference: Clear, Solid, and Tint. The semi-vacuum sealed Breadvac keeps moisture and air from spoiling your stash. The 2-way air valve lets gas build up seep out little by little without inviting in more oxygen. You can store pretty much anything in the Breadvac--from coffee beans to cane sugar--but if you do happen to store dry herb, TightVac advises you to keep it in strong ziploc bags inside the Breadvac for a smell-proof experience.
