Thank you for viewing! This is a storage solution for N gauge model trains, compatible with the Yamada Kagaku SHIKIRI 0 sold at 100-yen stores. It's an original product, uniquely designed and manufactured in a domestic factory. * This product does not include a case. Please purchase one yourself, as it is a standard item at many 100-yen stores like Seria, Can Do, and Daiso. * Suitable for storing 15-21.5M class N gauge model trains. * Includes a set of three items: 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 pack it under the trains to provide support. Alternatively, you can wrap the trains in thin paper before storing them. * 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 (Set of 2) Urethane inner sheet that turns a 100-yen store case into a 7-car N gauge storage case. ※ Caution!
