Transformers SG-37 Galaxy Upgrade Optimus Prime + DK-13 Upgrade Kit Used item. The upgrade kit was already attached at the time of purchase. Some parts are missing, and the original foot parts were also not included. The foot parts that attach for posing tend to fall off, so you might want to use glue. Stored in a zip-lock bag. Please refrain from purchasing if you are concerned, as this item has been handled by someone else.
