Review: Awesome, fun magnets for kids - My grandchildren have so much fun with these! They find so many ways to use them and it keeps them busy for a long time. They love to move them around on the table by putting one under it and one above it. They experiment by attaching them to other surfaces. The magnetism is really very strong. They enjoy them so much that I bought a second set because, when 2or 3 are playing together, there never seemed to be enough to go around. I also like the size and the color of these.

### ⭐⭐⭐⭐⭐ Great little fidget toy — my kid’s obsessed
*by H***4 on July 2, 2025*

My son loves these things. He’ll sit and mess with them while doing homework, watching TV, or just hanging out. They keep his hands busy without being distracting, which is kind of perfect. The magnets are strong, and there are enough pieces to build different shapes or just fidget with. Simple toy, but it’s been a hit in our house.
