Description

MJ Arsenal’s four-piece grinder is a straightforward aluminum workhorse: grinding chamber, screened collection chamber and kief catch, in a 2.2″ (56mm) diameter body. That size is the practical middle ground — big enough to grind a full bowl in one twist, small enough to stay in a pocket. Four anodized colors.

Why it stands out

• Four-piece design with a screen and dedicated kief chamber
• 2.2″ / 56mm diameter — a full bowl per twist without pocket bulk
• Machined aluminum body with a consistent tooth pattern
• Black, Blue, Green and Purple finishes

Care

Tap out the kief screen rather than brushing it hard; a bent screen never seats flat again.
