Enoden train set equipped with a light sensor function. - Model Name: Light Sensor Enoden 20 Cars - Features: Equipped with a light sensor function - Target Age: 3 years and older - Contents: Enoden train set Thank you for viewing. This item was won in a raffle at a railway event, but I am selling it because I will not be using it. The reason the item condition is listed as "slightly scratched or stained" is because the box on the back is warped. Other than that, the item is in good condition. Thank you for your consideration.
