This bundle includes two sets of two 28-ounce BlenderBottle Classic Shaker Bottles, perfect for mixing protein shakes, smoothies, supplements, and more on the go. One set features a moss and navy color scheme while the second set comes in an all pink and coral palette. Both sets utilize BlenderBottle's patented mixing system with a 316 surgical-grade stainless steel BlenderBall wire whisk that smoothly mixes contents. The leakproof screw-on lids create a secure seal, and flip cap snaps shut for easy transportation without spills. With two bottles in each set, you'll always have a clean bottle on hand. The wide mouths make adding scoops of powder and liquid ingredients simple, with clear ounce and milliliter markings for measuring. Bottles are durable BPA and phthalate-free plastic, top-rack dishwasher safe for easy cleaning. With coordinating colors across the sets, you can color code your shakes or match bottles to your gym bag. The sets complement each other nicely - keep one at home and one at the office or pack the pink set in your gym bag and the green set in your work bag. With two bottles in each set, you'll always have a clean blender bottle ready for your next shake.
