Natursutten Butterfly Rounded Small 0-6 mo (2 pack) Made with 100% natural rubber from the tree Hevea Brasiliensis. No BPA, PVC, phthalates, nitrosamines, chemical softeners, or artificial coloring. Uniquely hygienic, one-piece design, with no joints or cracks where dirt and bacteria can accumulate. Made in Italy-by a family business manufacturing rubber baby products for 3 generations. Allergen-free. (The protein that on rare occasions can provoke a latex allergy is completely eliminated during production.) Softer than silicone-unlike conventional pacifiers, won't leave marks on baby's face. Just like toothbrushes, pacifiers should be replaced every 6 to 8 weeks. Conforms to pacifier-safety requirements as determined by European standard EN 1400 and CPSIA.
