Review on 🌟 Discover the Radiant Elegance of NATIONAL GEOGRAPHIC Glowing Marble Glow by David Crawford

This set goes with the standard sets if you want to expand it but of course the glow in the dark balls are only visible when passing through they go through. transparent parts of National Geographic sets. Now we have about 500 pieces and the grandkids are having a lot of fun with them. After playing around with this set we got another glow in the dark set that didn't sell out at Revain (this one is the largest) and then added two smaller ones. It was her "big" Christmas present. They always make a "charging station" for the marbles (a flashlight to place under one of the clear set holders) to keep the marbles charged while playing, and that's not a problem. Have fun. The pieces can be stacked fairly high before the towers become unstable, but not as high as desired. However, the guys don't seem upset because the pieces easily fit together. That's 6, 8 and 10.
