Glitterbomb Super Jumbos

Glitterbomb marbles have a black base with flecks in a rainbow of colors covering the surface of each marble.  The surface has been iridized to give each marble an oily reflective sheen.  Super jumbos are approximately 42mm or 1 5/8" in diameter. They are sold in packs of 5 or 30 marbles.  Sizes may vary slightly.
