Silicone Straw Tops by Mason Bottle are a safe, non-toxic, and eco-friendly alternative to traditional plastic sippy cups and straws. Crafted from high-quality, non-toxic, BPA-free medical grade silicone, they are durable, reusable, gentle on teeth and gums and effortlessly attach to any regular mouth mason jar, our Silicone Bottle or Stainless Steel Jar. The innovative design allows you to use them as a silicone sippy cup without the internal straw for young toddlers, or attach the internal straw for older children who have already mastered drinking from a straw cup. The recessed “X-cut” flow control valve keeps leaks, spills and messes away while promoting safe oral development for your child. The versatile functionality makes our straw tops a safe, practical and easy to clean (say hello to the dishwasher!) choice for families during all stages of the feeding journey.
