These marbles are for my 6 year old grandson and I'm sure he'll be excited. By the way, I'm very impressed with your quick and courteous help. That means a lot to us consumers when ordering online. Thanks a lot!
Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
This marble has fantastic contrast and depth! The body of the marble is crystal clear. At the center is a shrunken core of black glass overlaid with a chevron pattern in white. A trio of 5-lobed swirls in white float on the surface of the marble. There is a significant layer of transparent crystal between the shrunken core and the floating swirls, adding depth to the design.
