Review on 🌌 Glowing Space Starter Marble Genius by Mario Bullard

Great toy. We bought this and a booster for our 3 year old son after he showed interest in building and playing with other marble toys. They're solid and perfect for allowing him to explore concepts like cause and effect and other STEM topics (kids' experiments are fun!). We were drawn to the glow-in-the-dark set because we intended to use it in a sunny room with LED lights and our other space-themed toys. They glow well and the flares are even more fun. We recommend them to the whole family. I hope they get some too so ours don't disappear after family reunions.
