Tightvac GrinderVac is an all-in-one dry herb container with a built-in grinder. Carry with you all you need -- .07L of dry herb, an airtight container that's odor proof and vacuum sealed, and an herb grinder to grind your dry herb down to a fine kief on-the-go. A moisture proof compartment with an airtight lid sits on the top of the Tightvac GrinderVac so you can carry nuggets of dry herb before grinding them. GrinderVac features an acrylic grinder with sharp teeth that grinds dry herb down in just a few twists. The included stir tool enables you to get the most thoroughly ground dry herb from your Grindervac herb container. The bottom of the Tightvac Grindervac boasts a lock cap that seals and unseals the Grindervac. The Tightvac GrinderVac herb container fits easily in your pocket so you can carry your dry herb with you wherever you go. You can also use the Grindervac to store your dry herb for long periods of time.
