The original 12mm spout that comes with the food bottle is made from food grade silicon. It is a soft mouthpiece that has a 12mm diameter opening that allows for chunkier type foods like oatmeals, chunky yogurts, and even tinned spaghetti!
5mm Spout
The straw spout is interchangeable with the original spout and is made from food grade silicon. It is a soft mouthpiece that has a 5mm diameter opening that allows for thinner type foods like purees, plain yogurts, and rice cereals.
