I was very impressed with your website. Found exactly what I needed to replace missing marbles for a game that I have. Also, I found some fun stuff for my grandchildren to play with while looking at this site.
Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
Transparent cobalt blue base swirled with opaque dark orange and light blue in and on the marble. 25 glass marbles (one of them is a 1" shooter!) with colorful printed header card. Don't forget something to keep the marbles in!
