The Spider Bottle Mini in Blue. The high-grade, patented SpiderBottle®, with its patented SpiderMix Spiral, is manufactured from highest quality, surgical-grade stainless steel. Spectacular mixing results and super-easy cleaning are guaranteed thanks to its high flexibility and cutting-edge design. Designed to hold 500 ML (16 ounces) of liquid, its a great size for nearly every use. In a downward-shaking movement the flexible SpiderMix® swings out through the SpiderBottle®, oscillating and sweeping over the complete cup area and perfectly mixing your ingredients like a wire whisk for the best mixing result ever! With an upward-shaking movement, the flexible SpiderMix® contracts in the form of a strainer and mixes together the passing fluids. Due to the constant contraction-and-expansion movement of the SpiderMix®, lumps and clots are completely eliminated and a perfect mixing of the ingredients is guaranteed. The variety of applications for the Spider Bottle are diverse and unlimited.
