Here is a great opportunity to own a collection of vintage American Flyer #25 smoke cartridges. This set includes 6 boxes of 12 cartridges each and a dealer box. The smoke cartridges are made of soft plastic and are designed for the 3/16 scale locomotives with smoke units. These smoke cartridges are perfect for model railroaders and collectors alike. They are made in the United States and are compatible with S gauge trains. The yellow color adds a pop of fun to any train set. Don't miss out on this rare find!
