This is a Plarail train case, a two-tiered set. Approximately 46 x 29 cm. No fixed connecting parts or other accessories are included. It can also be used as a track, which is recommended. I used it as a storage case for about a month. My child hardly played with it as a track. Please understand that this is a used item. I would like to sell it to someone who doesn't mind stains that won't come off, minor scratches, and other signs of aging. Thank you very much.
