Simple, brilliant, and just a little hip - The Mason Bottle can turn any mason jar into a bottle. You can store, heat, and serve milk in this streamlined and safe little bottle.
Available in 4 oz and 8 oz size. Each bottle includes one silicone nipple, a plastic cap, and regular-mouth mason jar complete with metal lid and collar.
All Mason Bottle nipples are made from medical-grade silicone. The nipple uses a dual-valve ventilation system that mimics the human body. Milk flows smoothly to reduce gas and colic.
