The seriousness of these magnets is so insane that I have just copied the entire quote below! Please go to the following link to see the full list of information! These are extremely dangerous especially of little ones.  Click here to go to the website recall.

The risk assessment on these magnet sets has informed Health Canada's determination that they are a danger to human health and safety because they contain small powerful magnets which can be easily swallowed or inhaled by children. Unlike other small objects that would be more likely to pass normally through the digestive system if swallowed, when more than one small powerful magnet is swallowed, the magnets can attract one another while travelling through the digestive system. The magnets can then pinch together and create a blockage and slowly tear through the intestinal walls, causing perforations.

The results of swallowing small powerful magnets can be very serious and life-threatening. Swallowing incidents have often resulted in considerable damage to the gastrointestinal tissues and required emergency surgical treatment. For survivors, there can be serious long-term health consequences.
