I had alot of fun on this site and the hardest part was narrowing down my choices. I came on to buy some marbles for my own son and ended up purchasing materials that I will use with my whole cub scout den.
Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
Iridescent crystal clear glass swirled in and on the marble with opaque pink. 25 glass marbles (one of them is a 1" shooter!) with colorful printed header card. Don't forget something to keep the marbles in!
