Introducing the Jaq Jaq Bird x Hello, World! Limited Edition collection! Making every effort to encourage analog play among children, Jaq Jaq Bird continues to expand upon our mission of unplugged creativity through a brand collaboration with the Hello, World! book series, written and illustrated by Jill McDonald. Hello, World! teaches young children about STEM by exploring different aspects of natural science, including dinosaurs, our solar system, backyard bugs and ocean life. Rediscover wonder with Jaq Jaq Bird x Hello, World!, and nurture curiosity by allowing little ones the creative freedom to learn about and illustrate the world around them. Our Doodle It & Go erasable book contains eight blank pages and a set of four ButterStix®. Simply wipe your book clean with a damp cloth to erase your mess-free ButterStix® markings, and create over and over again. Ideal for children 3 years & up. Each book is 8"x8" when closed.
