For the thickest blends, Twister Jar Blender Accessory features all of these unique advantages: extra-strong, patented single-prong tuned wingtip blade and easy-to-read jar. To use the jar, simply add ingredients and twist the lid counter-clockwise while the blend cycle is running. This twisting motion forces the ingredients from the sides of the jar back into the blade, allowing you to achieve a perfect blend every time.
