Query: Leaves residue - Use for display only

I loved Slinky as a child, gave one to each of my kids, and keep one on my desk at work to use when I need to think thru a problem. This particular slinky leaves a black residue on your hands that requires soap and water to wash off. It comes off so easy that I assume it would dirty your clothes too. I do not recomend this 1945 Collector's Edition for children or for anything more than a visual display. Buy the silver one if you want to handle it.
