You won’t find a higher quality grinder anywhere in this price range. We custom engineered this Anodized Aerospace™ Grinder to the highest standards. The Screen is kept in place by 3 strong magnets, and is easily removable for maintenance. The diameter of the holes are also larger than average to help prevent clogging. You will notice the smooth operation and incredibly strong double magnet which creates a virtually air tight seal. At Vape World our customers are our priority. We want you to be excited to visit us for all of your aromatic needs. If you have questions, or need anything at all please let us know, we would love to hear from you!
