Inside the 20oz cup, permanent engraved markings clearly show up to 16oz for accurate pre-workout ratios—no guesswork, no sticky mess.. [Odor-Free 304 Steel & Ergonomic Carry Handle] Crafted from BPA-Free 304 stainless steel, this shaker won't absorb yesterday's protein smell like plastic bottles do—every drink tastes clean and fresh. The flexible handle and rounded body provide a comfortable, secure grip, while the durable metal construction handles daily wear and outdoor adventures.
