This set was a favorite of ours and was enjoyed by my little one on many car trips. Not only are they learning letter recognition, they learn to write their letters! The carrying case is strudy and makes it easy to take along on trips or to keep little ones entertained at any time. We started using these at age three and my little one just grew out of them an she is six. Now it's time to pass them on to another child who will love them as much as we did.
