The Cooler Shaker is a 700 ml capacity version of ShakeSphere’s shaker bottle that adds a “cooling” capability. It uses double walls with food-safe gel capsules placed between them. After freezing, those gel capsules keep the inside of the bottle chilled, extending the time your drink stays cold.
It supports the same capsule-shape design with no mixing balls or mesh, letting you shake powders (or puree soft fruit) cleanly, reducing residue and smell.
