Eye-catching and entertaining, our glittering pool balls are clear and have thousands of reflective particles ("glitter") suspended in the resin. The high-balls ("stripes") are clear and have a "core" cast inside of their identifying color. The low-balls ("solids") are transparent, in their regular color. The numbers are engraved on the balls in white. They are regulation size, 2-1/4" in diameter, and weigh 4-1/4 oz.
