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, uniquely designed and manufactured in a domestic factory. * This product does not include the case. Please purchase it separately at 100-yen stores like Seria, Can Do, or Daiso, where it's a standard item. * 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. * Carefully remove the urethane foam. Pulling it off forcefully may cause warping. * The model trains in the images are for illustrative purposes only and are not included. * As it is a new product, there may be a chemical odor upon opening, but it will dissipate in about two weeks. * If you are concerned about the inner sheet warping, please purchase the separately sold spacer sheet and use it as a support on the bottom side of the trains. * 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 10) Urethane inner sheet that turns a 100-yen store case into a 7-car N gauge storage case. ※Caution!
