Precision Grind Adjustment – A full 12-click rotation with 20 μm incremental steps lets you dial in grounds for every brew method—from espresso to French press—and seven CNC420 high-carbon steel burrs (55–58 HRC hardness) ensure consistently uniform particle size.
Ultra-Portable Slim Profile & Pure Aluminum Body – Crafted from aerospace-grade pure aluminum, this 15 cm × 5.5 cm grinder is both feather-light and rock-solid, fitting effortlessly into backpacks or pockets for camping, hiking, or road-trip brewing.
Durable, Washable Glass Jar – The deep brown–tinted glass jar is both elegant and functional: fully washable, odor-free, and transparent enough to monitor beans without compromising purity.
Generous Bean Capacity – Holds up to 25 g of coffee beans—enough for one to two cups of rich, fresh brew without constant refilling on the go.
Optimized internal gearing minimizes hand fatigue for smooth, easy grinding, while delivering uniformly ground beans that extract into a cup brimming with flavorful oils and a silky crema.
