This wooden magnetic set is colorful, decorative, reliably magnetic and educational, too. Contains 40 wooden pieces measuring 1-3/4'' tall, each with full magnetic backing. They come in a cute re-sealable milk carton package that measures 8-1/2 x 3-1/2 x 2-3/4'' and closes with double snaps. These wooden letters are environmentally friendly too: the pieces contain 80% recycled wood and the packaging contains 85% recycled paper. For ages 3 and up.
