This Blafre flip-top spout converts standard bottles into an easy-to-drink sippy cap designed for toddlers and young children. This leak-proof lid stays sealed when the spout is closed and opens smoothly to reduce spills and mess while drinking. This spout is made from safe, non-toxic plastic for everyday use and provides a durable, premium-feel bottle accessory. This lid fits all Blafre bottles, and buying an extra straw allows quick conversion to a straw bottle—straps sold separately. This easy-to-attach, simple-to-clean design is ideal for school bags, daycare, and on-the-go hydration.
