I bought theses because I felt they would be a great way to introduce musical instruments to help my grand daughter. These instruments have the ability to help stimulate musical interests in older toddlers and/or preschoolers. They also can help them develop a sense of rhythm. They are the perfect size for their little hands. Plus, they make sounds without being overly loud. (They are patent friendly).
They can also be used at parties for preschoolers. Mine came with 6 stainless steel bells with nylon handles for the wrist and 3 Wooden Maracas.
