The high powered magnets sets were labeled “Ages 13+” and do not meet the mandatory toy standard F963-08 (effective August 17, 2009) which requires that such powerful magnets are not sold for children under 14. Magnets found by young children can be swallowed or aspirated. If more than one magnet is swallowed, the magnets can attract each other and cause intestinal perforations or blockages, which can be fatal.
