If you want to add some color to your collection, but prefer to keep things discreet - check out this grinder called the Chameleon. Made with zinc, the grinder is anodized for more durability, but the process also gave it an eye-catching iridescent effect. The color of the grinder constantly changes and reacts to different lighting conditions, making a cool effect without being overpowering. The interior of the grinder hides four pieces, including a top chamber with sharp diamond-shaped teeth and a magnetic lid. The finest pollen will sift through the screen and end up in the bottom chamber, and you can collect it with the included scrape tool. This zinc 4-piece grinder measures 2.2 inches in diameter.
