This case can hold up to 5 N-gauge model train cars, sized 15-18 meters. I designed the inner lining myself and had it manufactured at a domestic factory because I found it troublesome to take out the cars from paper box sets, N-gauge converted Tetsudo Collection models, and cars in clear cases. Removing the center urethane allows you to store 15-meter class cars. There are two notches on each side, and by cutting them, you can store cars up to 18 meters long. 【Main Compatible Cars】 ◯ Kiha 100 ◯ Kiha 120 ◯ Oha 35 series ◯ Diesel cars and LRV cars made by Niigata Transys up to 18M class 【Product Specifications】 Case: "Shelby Partition Case Middle" available at 100-yen shops Top: Durable 3-layer bubble wrap Inner lining: Original design Bottom lining: Made of the same material as the inner lining Size: A5 (approx. 155mm long, 185mm wide, 30mm high) Other: The center and bottom car sections can also be used as parts cases ※Notes※ ・Each car is an example and is not included. ・Not compatible with cars over 18.5 meters. ・Shipped via Yu-Packet Post.
