The Glowing Amulet is shown in its normal condition (neon yellow). The ball will charge with exposure to any light source (5 minutes in the sun or under a black light works best) and then, unlike other "glow" balls that only work under a black light, when the charged Amulet is placed in a dark area it will continue to glow for hours.
The core is the inner portion of the Gargoyle with a larger spherical wrap. This is then surrounded with a new phosphorescent hard URETHANE cover (patent pending) that truly GLOWS-IN-THE-DARK. This ball contains NO radioactive materials but due to the special chemicals involved to create this ball, slight color variations and light streaks might be found throughout the cover stock. These streaks are NOT defects and in no way effect the performance or integrity of the ball.
Although this ball is designed as a spare ball, the urethane cover and dynamic core create a great ball for dry lanes or for crankers. Drill it like you would any other 2-piece ball (stacked, leverage, etc.) This may make the ball a little more aggressive for spares than some people like. For a straighter spare ball, drill it very tame and balance the static weights out to close to zero (top, side, and finger). For even straighter roll, use a ball with low top weight and drill the ball axis, placing a weight hole near or on the axis to produce 1/2 to 3/4 ounce negative side weight.
