This flip-top spout from Blafre makes it easier for the youngest children to drink from a bottle with a smooth, controlled sip and simple flip action. This leak-proof sip lid seals securely when closed and flips open to reduce spills during meals and travel. This replacement cap is made from safe, non-toxic plastic and fits all Blafre bottles; straws are sold separately so an extra straw can be added to any favorite bottle. This durable drinking spout works well as a spare or upgrade for water bottles and helps keep bags and car seats spill-free.
