Created in 2015, Mason Bottle offers parents and caregivers a non-toxic, eco-friendly glass baby bottle that pairs with standard mason jars. The brand designs plastic-free feeding products—glass and silicone bottles, stainless steel jars, and silicone tops—free of BPA, BPS, lead, and phthalates. Its mission is to eliminate plastics wherever possible, prioritize sustainable and USA-made materials, and keep products as minimal as possible. Every product is rigorously tested for 20+ toxins and heavy metals in a U.S. laboratory.
