The Blendtec Mini WildSide Jar is Perfect for single-serve blends, like single serve smoothies and salad dressings. The Latching Rubber Lid keeps vigorous blends in the jar, preventing accidental spills and drips. The Blendtec Mini WildSide Jar is more than just a container, it was designed with a patented fifth side meant to provide bigger and faster blends. Created with a blunt safety blade that is 80% thicker and ten times stronger than other blades, the Mini WildSide Jar can tackle any blending obstacle with maximum efficiency. Made from impact-resistant, BPA-free copolyester. Compatible with all Blendtec consumer blenders (not compatible with Blendtec mixers)
