Part of the morning ritual for freshly ground beans each day. Also a great option to pack away with an aeropress for top notch joe while travelling. This is Rhinoware's "V4" and was built to neatly fit inside the aeropress inner and smallest chamber. It is a little shorter then some other models in order to fit and grind about 25g once filled. Comes will a little attachment to help you grind directly into it.
