-Why Creating a Baby Bottle Out of Mason Jars has Made Us Who We Are- As new parents, we wanted to eliminate plastics wherever possible, prioritize sustainable and high quality, and be as minimal as possible-which meant only buying quality products with multiple uses. We built all these values into Mason Bottle, including a wide natural nipple shape to support the transition from breast to bottle and back. We launched Mason Bottle in November 2015. Every product we've launched since Mason Bottle still meets the same criteria that we've been committed to since day 1: - made from the healthiest materials available - highest quality to withstand years of use - multi-purpose and minimalist so you can do more with less - easy to clean and convenient to use - supports fair wages and local business. And we promise to uphold these standards as long as we're in business. Thank you for all of your support! - Laura, Seba, Pax, and Milo
