Frequently Asked Questions:

Q: Are the magnets strong enough for tall towers?

A: Yes. For the tallest builds, use the steel balls as junctions to spread the load.

Q: Is it safe for toddlers who put things in their mouths?

A: No. The set contains small steel balls and magnetic parts, so it is for ages 3 and up only. Keep it away from younger siblings and count pieces after play.
