The Wooden Animal Magnets by Melissa & Doug include twenty magnetic animals with full magnetic backing.  The Magnetic Animals in a Box can be used to practice the names and sounds of these twenty animals with your children or to teach them to sort the animals.  For example, you could sort them by animals in a zoo, animals on a farm, animals in the sea, etc. Use them on your favorite magnetic board (cookie sheet works excellent) or even on the refrigerator for individual play!  Store conveniently in a solid wood storage case with see - through sliding lid!  Non-toxic dyes-safe for children.  Ages 2 years+
