We have a lot of sons, and they've all gone through the �€�fire truck mania�€� phase. As a result, this puzzle has seen a lot of use in our home! Fortunately for us, this puzzle was made to withstand the rigors of being loved by lots of boys. The pieces are very thick and sturdy with a durable, wipe-clean finish. It is an ideal floor puzzle for beginners as it only has 24 pieces but measures an impressive four feet long when completed. Your little boy will have so much fun doing this puzzle over and over that he will never guess that he is learning logic and problem solving while improving his fine motor skills. This puzzle is highly recommended to bring a great big smile to any boy ages three and older!
