Arguably the best grinder on the market, this small statured piece is must have for any vaper. Beautifully crafted from top-quality, premium materials and machinery, the 4pc Space Case Grinder Small 45mm is durable and will survive a long time through the wear and tear. This grinder also incorporates scratch resistant material making for a smooth polished finish. The razor sharp diamond cut teeth work to grind the stickiest materials with ease as the magnets hold the grinder together with superior closure. The 4pc Space Case Grinder Small 45mm is broken down into 4 separate pieces. The top part of the grinder employs the sharp teeth that will finely and evenly grind your herbs. When the dry herbs are at the right consistency, they will fall through the holes to the second chamber. As they fall, pollen also falls through to the stainless steel screen making it easy for collection. The bottom chamber stores pollen for later use. If you are looking for an impeccable, high-performance grinder the 4pc Space Case Grinder Small 45mm is the perfect choice.
