Two 600ml shaker bottles for protein powder, with mixing balls, graduations and leak-proof design.

Appearance and Accessories: The image shows two shaker cups (purple-red and black). These cups are made of plastic (usually food-grade polypropylene) and have a flip-top lid and a handle. Two metal mixing balls are included on the right; these can be placed in the cup and shaken to completely dissolve powders and prevent lumps from forming.

Uses: Frequently used in gyms and while traveling, this is a portable tool for athletes to supplement their nutrition. Some models are also graduated for easy measuring.
