Our busy book binder is super durable and keeps all activities organized, so children can bring along to learn in the car, when visiting grandma, and everywhere else! Every activity piece is smooth with rounded edges and has Velcro already attached on the back so children can put them in place with a simple press. We use high-quality, super sturdy materials which are easy and safe for children to handle, so they can play alone, with siblings, and with friends.
