A three-layer plastic shaker bottle for carrying drink ingredients separately. The modular storage layout keeps powder or other dry ingredients apart from the liquid until you are ready to mix.
The source describes a secure, leak-resistant lid, but provides no test rating. Check that the lid and storage sections are properly closed before carrying. Mixing results vary with ingredients and quantity; a completely lump-free shake is not guaranteed.
Capacity, plastic grade and hot-liquid compatibility are not supplied. Follow the manufacturer's use and cleaning instructions.
