Although magnets can be wonderful toys and highly educational, these are 'adult' toys, and not for children. Small children should not be allowed to handle any of our magnets at all! Older children should handle them only under adult supervision, and wearing proper safety equipment (depending on the size and power of the magnets being used). Large magnets should be handled with extreme caution. Small magnets could cause serious complications if swallowed - keep well away from children.
