FourSide Jar™
The Original Square Jar
The FourSide jar effectively harnesses the power of your Blendtec blender.
- Blunt safety blade is thicker and stronger than other blades
- Made from impact-resistant, BPA-free co-polyester
- 1 year warranty
- Compatible with all Blendtec consumer blenders
The FourSide is ideal for:
- Ice cream
- Grinding grains
- Soups
- Smoothies
- Dips and Batters
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.
