This is a set of urethane dividers designed to hold up to 5 model train cars, suitable for 15-18 meter class vehicles, and designed to fit in the "Shikiri Case Middle Shikiri Ita BK" sold at 100-yen stores. I designed this myself because I found it troublesome to take out and put away model trains from paper boxes, N-gauge converted Tetsukore models, and clear cases, and I commissioned a domestic company to produce this original product. By removing the urethane in the center, you can store 15-16 meter class vehicles. There are two notches on each side, and by cutting them, you can store vehicles up to 18 meters in length. ※Notes※ ・Not compatible with vehicles over 18.5 meters. ・Each vehicle is for reference only and is not included. ・Although this is a personal sale, I regularly order urethane, so there are no supply issues. ・Since it is new, there will be a chemical odor for about two weeks after opening. ・While the cost performance is good, I recommend purchasing this product after obtaining the case. Please experience the comfort of storage for yourself. You will be freed from the troublesome tasks of opening paper cases and plastic cases, and you will feel that you have more time to run your trains. The price is based on the Yu-Packet Post shipping cost to keep it low. Therefore, I may not be able to respond to requests for combined transactions. Thank you for your understanding. You are welcome to remain silent throughout the transaction, including greetings. I may also do the same. I apologize. Thank you for your consideration.
