If you plan to grind up some bud in space, reach for a 4-piece herb grinder from Aerospaced. Made from 6061 aircraft-grade aluminum, there's no chance of rust or damage to the razor-sharp teeth, even if you decide to take it into orbit. Each of the diamond-shaped teeth are carefully placed for an extra-fine and consistent shred. The top is secured with high-strength neodymium magnets and optimized threading so it's easy to turn. Aerospaced grinders come complete with a kief screen and scraper to collect and remove fallen trichomes without getting sticky fingers. The grinder has an anodized finish that comes in four colors: gold, red, orange, or black.
