The Melissa & Doug Scratch Art ABC & 123 Writing Pad is a creative way to learn and practice the alphabet and numbers! Use the included wooden stylus to follow the arrows and scratch away the black coating while tracing and writing letters and numbers. Scratch more and reveal vibrant colors and matching pictures! The stylus stores in the cover of the 12-page spiral-bound pad, making it a fun and convenient screen-free travel activity for kids five and older and families on the go!
