This is an authentic LEGO product. I have reassembled it and confirmed that all the pieces are present, but as I am not a professional, I cannot guarantee that there are no overlooked or missing pieces. Please understand that this item has been opened. The stickers were applied by a child and are slightly crooked. The instruction manual is included, but it shows signs of use, with some bending and folds. The last page has circles drawn on the parts with a pencil. The box is not included. The item will be partially disassembled for shipping. Thank you for your understanding.
