Review on Non-Toxic Magnetic Educational Stacking Building by Matt Nichols

Cool. I like both sizes very much, although with a larger set you get a little more for your money. My project is to make one big tetrahedron out of 120 smaller ones. It's easy to do with magnetic sticks and non-magnetized balls. I wish they had 10 colors instead of 9, but that wouldn't matter for most projects.
