Convenient paper pack nipples, made of plastic and easy to use. Set includes replacement nipples for paper packs. All items, including the nipples, are new and unused. I purchased these with the intention of using them, but ended up not needing them, so everything is new and unused. The nipples are included, so you can use them right away. These nipples can be directly attached to paper pack beverages. Drink directly from the paper pack without needing a bottle. Suitable for all ages, from newborns to weaning. Recommended for hydration on the go and as a stockpile for emergencies. Convenient to carry, reducing luggage and hassle. - Color: Blue - Type: Bottle nipple - Material: Plastic Thank you for looking.
