These are Star Wombat3 misprints. They are listed by weight and color. Stamps will vary.
Innova says, "Great Feel, Straight Flight. The Wombat3 mid-range feels great in the hand and is easy to throw. The VTech rim and lower profile adds extra torque resistance, great for sidearm throws. Straight shots still go straight while turnovers stay turned with a gentle landing."
