The Nuby ID1538 soft Vari-Flo™ silicone nipple with a wide neck is a set of two replacement nipples for wide-neck bottles, recommended for babies 6 months and older.

• Material: Made from soft silicone, gentle on the baby's gums and teeth.
• Vari-Flo™ System: The built-in, pressure-sensitive valve allows the baby to control the flow of liquid by sucking from the nipple.
• Leak-proof design: When suction stops, the valve closes to prevent dripping and leaks.
• Anti-colic air vents: The air vents at the base of the nipple help prevent vacuum formation inside the bottle, which may reduce gas and discomfort.
• Wide neck: The nipple is designed to fit all wide-neck bottles and cups in the Nuby range.
• Easy cleaning: The one-piece silicone nipple with integrated valve is designed for easy cleaning.
