Smoke stacks to replace the rubber ones in the Leader Class Optimus Prime figures. Simply remove the rubber ones and insert these.
Note: please make sure that you've done any painting/effects to these before install. The Strong & Flexible material won't take several installs and removals. I've opened up additional materials, however, please be aware that only WSF has been tested.
