FORME is a sleek and smartly designed shaker packed with useful features to make supplementation easy. From the silent shaker mechanism and 35g built-in storage container to the 500ml double-wall insulated stainless steel body, this is the last shaker you'll ever want or need. Please note, this FORME comes with a 35g storage container as standard. You do not need to purchase an additional 35g storage container but you can do if you want extra storage containers.
