I was thinking about this the other night; noticed my Warrior's Rings on the shelf glowing as I turned off my office lights.
For those unfamiliar, the "Warrior's Ring" was the glow in the dark ring that came with Trap Jaw and Tri Klops.
I'd love to have a metal/pewter/whatever Warrior's Ring to wear. Losing the glow in the dark feature would be a small price to pay!
Why has there never been a metal one produced? Maybe there has been one and I just cannot find it.
