With a new little one, I'm always on the search for products that fit our lifestyle, and the Mason Bottle does just that! It's lightweight, easy to clean, and easy for little hands to grab. I also love that it doesn't serve just one stage of my little one's life. It can grow with him, too! From bottle to snack cup, the Mason Bottle will be a product that stays with us for years to come. The rust-free ring is a huge plus, too!
