Lifefactory's 9 oz glass baby bottles come with Stage 2 (3-6 mos) nipples.
9 oz Flat Cap bottles are leakproof and pack well in lunchboxes and backpacks for school-age kids and fit easily in purses for on-the-go moms.
The baby bottles are made of the highest quality, thermal shock resistant borosilicate glass. This allows the bottles to transition safely from freezer to boiling water.
The silicone sleeves provide a good gripping surface for little hands and help protect against the occasional drop.
