Why buy two products instead of one? The GrinderVac from TightVac is a grinder and a sturdy transport box all in one! Made of strong military-grade plastic, it is waterproof and will hold up to 10 grams of herbs.
You will find in the picture two diagrams that will help you get a good grip on your GrinderVac. Thanks to its simple mechanism it will keep your herbs away from light and humidity for a long time. Simply open the valve and close/open the lid by turning it. Inside, a "shark teeth" type grinder will chop your material very finely. It comes with a TightPac Poker to remove all the particles and not lose a crumb from your mix.
An indispensable tool at a minimal price!
