What will the guest at your party build with the Construction Deluxe Favor Kit (for 1 Guest)? We've assembled a favor box, inflatable hammer, wacky whirler, construction truck toy and truck erasers. Kids can pretend to hammer around the house, just like mom or dad does when fixing things. The dump truck is the perfect toy to take carry around so the child has something to play with wherever he is. Order a set for every guest at the party plus an extra for the birthday child.
