Blendtec products are built to the highest commercial standards. No tamper/plunger needed. Commercial-grade jar is compatible with all Blendtec blender models (not compatible with Blendtec mix n' Blend models). Reduce risk of allergen exposure by using separate color-coded containers. Versatility and customization for specific use. The Fourside jar's square shape blends much better than traditional round jars. The jar also generates more friction, heating soups and hot drinks quickly and easily. It's also especially good for grinding grains and making smaller quantities.

Made from durable Eastman Tritan polyester; lightweight material for easy lifting and pouring. 3 corners for simple pouring at multiple angles.
