Wow, this is great! I'm particularly pleased that they are the same weight as the original Glo-Balls, as that is a huge part about why I like that game so much. I doubt I'll use them in too many other things - the difference in ball weight really does make them play differently - but I am stoked to get some for VND!
Do you have any idea on pricing? Not sure if I'll be able to make Expo but might be able to ask a friend to pick up a pack or two for me
