Recommended for ages 1 and up Material: Plastic The mallet’s attached so it never gets lost. And it’s on wheels so toddlers can walk and pull their musical instrument wherever they go! Baby can start off by just tapping the keys with the attached mallet or pulling the Fisher-Price Classic Xylophone along (it’s on wheels!) By holding the string and pulling the xylophone along, little walkers will strengthen gross motor skills as well as their balance and coordination. Measures approximately 11 in x 5 in x 6 in
