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 shops. It's an original product designed in-house and manufactured in a domestic factory. * Suitable for storing N-gauge trains of 15-21.5M class. * Includes a set of three items: an inner sheet to hold the trains, a bottom sheet, and bubble wrap to cover the top. * Carefully remove the urethane foam. Pulling it off forcefully may cause warping. * The trains in the images are examples of storage and are not included in the product. * Since it's a new product, there may be a chemical odor after opening, but it will dissipate in about two weeks. * If you are concerned about the warping of the inner sheet, please purchase the separately sold spacer sheet and insert it under the trains to provide support. * 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 (N-Shell) (Set of 3) 7-car N-gauge storage case using 100-yen shop cases ※Caution!
