Michelle Walsh, who founded the company SafetyTat, says she created temporary tattoos and long-lasting write-on skin stickers after visiting an amusement park with her kids. In case her family got separated, she scrawled her phone number on her kids' arms with a ballpoint pen as a safety measure. That gave her the idea that a warning label on the body could be useful to other parents. Her sister-in-law's son, in fact, was prevented from eating a salad with peanut oil dressing after a server noticed the sticker on his arm warning of his severe peanut allergy.
Other companies have also developed safety tattoos, but not everyone is a fan of the temporary tats, noting that it could lead kids to feel marginalized. What do you think of the tattoos?
