These crinkle books are perfect for babies! They're designed to help little ones develop their senses and learn through play. The high contrast colors make it easy for babies to focus, while the crinkle paper inside stimulates their hearing and touch. There are two styles available: Baby's First Devotional with Catholic devotions, or Baby's First Story of Saint Francis. They're made of 100% polyester, 5.5in x 5.5in, and the front and back covers have crinkle paper. Hand wash with warm water and mild soap, then lay flat to dry. Safety tested and passed ASTM F963, CPSC and CPSI.
