“Warning Balls”

Inspired by warning and caution symbols, these marbles were designed in response to the attack on the World Trade Center. Using the Graal technique, there are currently two patterns, the Broken Arrow and the Broken Wave, in various yellows. Each has both poles finished to a perfect closure. Mark refers to this as having  “2 North Poles.”

Sizes: 3 inches to 3 5/16 inches
