This bottle is the first NUK bottle with a narrow shape and a wide neck opening. The NUK Classic Bottles are easy to handle and save space when stored away. They also fit into all conventional bottle warmers. Because of its wide neck this bottle can be used with the NUK First Choice teat.

The NUK First choice teat features an orthodontic shape, extra wide lip support and an extra soft tip, simulating breastfeeding as much as possible. The similarity between teat and nipple is so close that babies hardly notice a difference when transitioning to bottle feeding.
