A brief "How-To" video demonstrating my technique for swapping out old o-rings in my vintage 80's G.I. Joes. I've always believed the o-ring to be the "soul" of these figures. Replacing a worn out, dry-rotted o-ring with a fresh new one gives the figure a brand-new lease on life. With proper care and maintenance, these little plastic people might live so many lives that you could possibly call them...IMMORTAL.
