The Mini HerbSaver is a feature-packed grinder that’s small enough to fit in your pocket. The teeth are extremely tough and will break down your herbs into a nice fluffy consistency. The Mini HerbSaver also has a magnetic lid that stays on tight, and it's also water and smell resistant. The Herb Saver Mini even has a keef screen and scoop as well! The screen of the Herb Saver can be removed easily for cleaning. And if that's not all, the Herb Saver Mini is backed by a lifetime warranty from the manufacturer.
