Use them to build geometric shapes, fractal patterns, mini sculptures, abstract art, or simple stress-relief stacks while you work, study, or brainstorm. The strong magnetic pull and precise cube shape make every snap and alignment feel clean and satisfying.

Q: What’s the difference between 3mm, 4mm, and 5mm cubes?

A: 3mm is ultra-compact and ideal for detailed builds, 4mm is a balanced everyday size, and 5mm feels chunkier and more tactile with stronger “in-hand” feedback.

Q: Are these magnets really N52?

A: Yes, they are made from N52 grade neodymium, one of the strongest commercially available magnet grades, which is why they snap together so firmly.

Q: Are they safe for kids?

A: These are not suitable for young children due to small size and strong magnetism. Recommended for ages 14+ and must be kept away from children who might swallow small pieces.

Q: Can I use them as a fidget toy at work?

A: Absolutely. Many people keep them on their desk to reduce stress, stay focused, and keep their hands busy during calls, meetings, or thinking time.

Q: Do they come with a storage solution?

A: Yes, each set comes in a metal gift tin, which makes storage and transport easy and keeps the cubes together.

Q: Will the cubes lose magnetism over time?

A: Under normal use, neodymium magnets retain their magnetism very well. Avoid extreme heat, crushing, or violent impacts to maximize longevity.
