This is Blendtec’s large 64 oz Jar/ Jug with lid has markings up to 1 litres but of course can hold more (64 oz is just short of 2 litres). Blendtec patented polycarbonate jars are stackable and feature easy-to-read markings. The ergonomically desgined jar allows 3-way pouring. The five-sided design creates a vortex within the jar that pulls the product through the blade area faster, reducing cavitiation and eliminating the need for a plunger or tamper.
