Thank you for viewing! This is a storage solution for N gauge model trains, compatible with the SHIKIRI 0 case made by Yamada Kagaku, sold at 100-yen stores. It's an original product designed and manufactured in a domestic factory. * This product does not include a case. Please purchase one yourself, as they are standard items at many 100-yen stores like Seria, Can Do, and Daiso. * It can store N gauge trains of 15-21.5M class. * The set includes an inner sheet to hold the trains, a bottom sheet, and bubble wrap to cover them. * Please remove the urethane foam carefully. Pulling it off forcefully may cause warping. * The trains in the images are examples of storage and are not included in the product. * As it is a new product, there may be a chemical odor after opening, but it will disappear in about two weeks. * If you are concerned about the warping of the inner sheet, please purchase the separately sold spacer sheet and use it as a support on the bottom side of the train. * If you are concerned about scratches on the trains, please protect them with thin paper. Combined transactions are possible, but to keep prices down, the price is based on the Yu-Packet Post shipping cost. Therefore, we may not be able to accommodate all requests. Thank you for your understanding. This product is sold year-round. We would appreciate it if you would follow us from our profile. You are welcome to complete the transaction without any communication. Thank you. Nshell Urethane inner sheet that turns a 100-yen store case into a 7-car N gauge storage case. ※Caution!
