Using this box car kit is easy. First, take out all the parts from the original box carefully according to the instructions. You'll notice the one - piece resin body and the separate underframe. Assemble them step by step as shown in the guide. Don't forget to use the decals for a more realistic look and follow the painting and lettering information. Since there are no trucks or couplers included, you'll need to get those separately if you want a complete model. When handling the kit, be gentle as the resin parts can be fragile. Store it in a dry and cool place to prevent any damage. If you're not satisfied with your purchase, let us know within 30 days and we'll refund your money. Just remember, you'll be responsible for the return shipping costs unless the item arrives damaged.
