The Comandante C40 MK4 Manual Coffee Grinder – Redesigned

The all new Comandante C40 MK4 Manual Coffee Grinder redesigned mounting of the upper bearings and axle prevents coffee beans from getting stuck. This redesigned feature is a major improvement from the previous version which increases its grind efficiency & reliability.  MK4 also comes with a clear polymer grind jar that helps attract dust and bean casings simply because the material has more static compared to glass.  By removing this excess dust and casings from your grind it can have a slightly improved taste.
