3 years & up. Hands-on learning that's easy, educational and fun! Colorful individual cards teach letter and number formation as children develop the fine motor skills necessary to learn to write letters and numbers. Also included in the Numbers & Counting set, are early educational activities such as counting, math concepts and simple shapes. Twist, bend, or simply press down -- no glue, no mess, and endlessly reusable! Buy the individual card sets, or buy both sets together, as a kit. Scent-Free. Made in the USA.
