Made from 100% natural rubber, from the tree Hevea Brasiliensi, natural rubber is softer than silicone and won't leave marks on baby's face. Larger shield touches the nose, comforting baby and more closely simulating breastfeeding. Uniquely hygienic, one piece design, with no joints or cracks where dirt and bacteria can accumulate. No BPA, nitrosamines, PVC, phthalates, chemical softeners, or artificial coloring. Made in Italy by a family business manufacturing rubber baby products for 3 generations. Sizes: LARGE +12 mo,
