They are not strong. I would not recommend it. My kids are young and have already broken a few. Very dangerous as the magnets fall out immediately. Now I'm just very careful when they take them out to play. If your kids are older, they'll probably be fine, although the magnetic attraction isn't as strong as some other sets.
