With our exclusive ON shaker cups, mixing-up even the largest and thickest protein or meal replacement shake is a snap. Each shaker cup has a portable 28oz capacity and a 3 ¼” opening at the top that makes adding full-size ice cubes a simple proposition. Last, but certainly not least, we’re proud to say that our shaker is BPA-free and made in the USA.
