This wooden number puzzle is well made and doesn't have any rough edges. The pieces are large enough for toddlers to manage. Just wipes clean after playtime. This is a great way for your toddlers to practice dexterity, eye hand coordination, learn numbers, counting, shapes and colors. To the toddlers and small kids it's just fun but, you know they are learning at an early age. If you or someone you know has kids this is a great item as an any occasion gift. My Great Granddaughter loved it! It's fun for boys or girls so order today.
