Measuring a perfect 2.5kg/5.5lbs., the Rock Weight is as functional as it is beautiful. You can add the weight into your current workout routine or use it to remind yourself to workout while working. The Rock Weight uses the beautiful Green Forest marble pattern. With a mostly green color, you can see the striking detail of the marble from any and every angle.

Every time you lift it to access your papers, your arm will thank you for the brief yet challenging workout.
