What is the silicone nipple/spout travel cover made of?
The nipple/spout cover is made of silicone with no added chemicals and is plastic-free. Silicone, which is non-toxic, is made from silica, the most common constituent of sand. It is a great alternative to plastics, rubber, or latex. The nipple/spout cover is FDA certified and can also be used as a small snack cup if desired.
