Thank you for viewing! This case can hold up to 4 N-gauge model train cars, sized for 20-21 meter class vehicles. It's perfect for storing cars from starter sets, boxed sets, iron collections converted to N-gauge, and cars in clear cases, making it easy to take them in and out. Originally, I designed this myself because I found it troublesome to organize my collection. It's an original product manufactured by a Japanese company. Removing the center urethane allows for 20-meter class vehicles. Removing the urethane on both ends allows for storage of vehicles up to 21 meters in length. 【Product Specifications】 Case: "Partition Case Middle Partition Plate BK" available at 100-yen shops. The case can be easily replaced if damaged. Top: Durable 3-layer bubble wrap, the most rigid type, also used for packing art pieces (d42L). Liner: Original product.

A case for streetcars, etc., is available, so please purchase that one. ・Although I am an individual seller, I place orders regularly, so there are no issues with supply. ・Shipping will be via Yu-Packet Post. The packed thickness will be about 33mm, so please check if it will fit in your mailbox before purchasing. ・The cases are new, sourced from retail stock before they are put on shelves, but may have minor scratches from the beginning. ・As it is new, there may be a chemical smell after opening, but it will disappear in about two weeks. If you are unsure if your vehicles will fit, please feel free to ask in the comments section. The price is set based on the Yu-Packet Post shipping cost to keep it affordable. Therefore, I may not be able to accommodate requests for combined transactions. Thank you for your understanding. You are welcome to remain silent throughout the transaction, including greetings. I may do the same. Sorry. Nshell N-gauge case using a 100-yen shop case (20-21M class, 4 cars) ※Warning! High-priced, inventory-less reselling of this product is rampant on Amazon.
