THERE’S ONLY ONE BLENDERBOTTLE® Everything else is just a shaker cup. The BlenderBottle Classic revolutionized the industry back in 2004 with its leak-proof seal, iconic design, and the BlenderBall® wire whisk. Now, years later, it’s still the best-selling shaker on the market. Why? Because it works. SMOOTH TASTES GOOD Say ‘goodbye’ to lumpy protein shakes and ‘hello’ to smooth, great-tasting drinks. Our patented mixing system uses the BlenderBall® wire whisk—found only in BlenderBottle® brand shaker cups—to mix even the thickest ingredients as you shake. 100% LEAK PROOF The Classic’s screw-on lid and secure flip cap keep your gym bag and car seat dry. With a snug twist of the lid and the assuring “snap” of the flip cap, you’re ready to roll. WORRY FREE Made from only the highest-quality materials, BlenderBottle® brand shaker cups are—and always have been—BPA and Phthalate free.
