Thank you for viewing! This is a storage solution for N gauge model trains, compatible with the SHIKIRI 0 case from Yamada Kagaku, sold at 100-yen shops. It's an original product, designed in-house and manufactured in a domestic factory. * Suitable for storing 15-21.5M class N gauge trains. * 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 inner sheet warping, please purchase the separately sold spacer sheet and insert it under the trains to provide support. * If you are concerned about the trains getting scratched, 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 remain silent throughout the transaction. Thank you. Nshell (N-Shell) 7-car N gauge storage case using 100-yen shop cases ※ Caution! High-priced, inventory-less reselling of this product is rampant on Amazon.
