Thank you for viewing. I previously purchased a large quantity of these as replacements for B-Train, but I am selling them because I have reorganized my B-Train collection and have surplus items. The products themselves are new and unused, but the sponge inside the case has discolored due to age. When shipping, the gaps in the carton box will be filled with air cap (bubble wrap) etc. The outside of the carton box will be wrapped in air cap for shipping. To prevent trouble and based on the principle of first-come, first-served, we cannot hold items or make them exclusive. (However, for items where price negotiations are taking place, the image may include the words "Under Negotiation") Please refrain from price reductions on this product. Also, regarding shipping, it may take some time to procure packing materials. We look forward to your purchase. Type of vehicle...Optional parts Type...Pantograph Manufacturer...KATO Type...DC type
