Lifefactory creates innovative, non-toxic products that make it easy to lead a healthy and eco-conscious lifestyle. They fuse modern sensibility, composition and exceptional utility to produce a glass beverage bottle that is free of known harmful chemicals such as BPA, phthalate, PVC and polycarbonate. All materials are FDA approved. The unique silicone sleeve is free of plastics, 100% non-toxic, provides a great gripping surface and helps prevent breakage. The benefit of using a glass beverage bottle is that there is no risk of chemicals leaching into your drink and no metallic taste. Great for toddlers, Lifefactory's sippy caps are leak resistant and have steady flow control. The sippy cap bottles provide a wonderful next step hydration solution as your child grows. Beverage bottles are easy to clean and dishwasher safe (the glass bottle and silicone sleeve can also be washed together in the dishwasher). Each bottle holds 9 ounces (250ml).
