Small chip flaking and colour bleed
The magnetic power was not as strong as i expected. There was also flaking of small chips from a few of the magnets, and the black colour rubs off into the hand easily. Definitely not for kids!But it serves its purpose and i got around the flaking and colour bleed by taping up a bunch of them together so that they are wrapped and safe to use.Edit: After about a week of usage, I am removing another star from my rating. the magnets are not touch and are prone to cracking and breaking. I have already had to throw 1 magnet that broke into 2, which two most have developed crack lines, while there additional flacking and chipping of small pieces on other magnets.
