Unlike permanent markers and art markers, which can contain chemicals harmful to animals, Animal Marker use "legal pigments," which are approved and regulated by the Japanese Ministry of Health, Labor and Welfare, for use in food, drugs and cosmetics. These pigments are nontoxic and devoid of any hazardous materials. For use on the rodent's coat. Color will not remain on the animal's skin
Electronic identification systems are more reliable and unalterable than traditional methods of animal marking such as ear punch, toe clips, or tail tattoo. When the reader is passed near the chip, it powers the chip by induction, then reads the unique transmitted signal to identify the chip. Nothing in the chip is vulnerable to time passage or repeated usage.
