About this Product


Air is the enemy to your dry herbs and tobacco. Don't let air dry out your herbs and tobacco so they get stale, dry, and tasteless. Use an Evak Airtight Stash Jar.

This innovative stash jar uses Prepara's twin valve system. When you insert the rubberized top into the stash jar, air will be forced out as you press down. This system is much better than a standard airtight lid because that type of lid traps stale air inside. You'll enjoy hearing the satisfying whooshing sound as the air leaves the jar. 

Evak stash jars are made of boro glass and stainless steel to make them durable and tough. These stash jars are good looking too so you don't have to hide them away unless you want to. 

When you use an Evak Stash jar, there won't be any air bubbles trapped inside nor any wasted space. Crystal clear, solidly built, and airtight, there's nothing not to love about Evak stash jars. 

Take your choice of any of the four sizes of this airtight stash jar. It comes in 8 grams, 28 grams, 50, grams, and 80 grams.
