Don't settle for the typical grinder, pick up a grinder with some personality like these super strong anodized aluminum colored 2 part grinders by Diamond Grind. The extra anodization process these grinders go through adds a vital extra layer of protection from scratching and any other wear and tear. The centered magnet keeps the grinder shut unless pulled open, letting the grinder double as storage for your material. Pick from one of the many available colors that suits your style.
The mini size measures 40mm (about 1.5") making it an awesome portable grinding option.
