Product as described for a 3 to 5 year old but it had almost been fully put together when we found a crucial nut was missing which fits and fixes and bolts into the metal frame fixing the frame but allowing the wheel to turn. No 'contact seller' box available or email address to request another nut. It would be too much to undo it all to send back. While we found a spare nut in a tool box, it is not an appropriate sized replacement and we can't find the same size, they seem to be specific to this toy. Please could one be sent? It has caused A great deal of disappointment as the wheel doesn't turn well.
