S.O.S. Tattoo creates temporary tattoos designed to help keep children safe during outings, activities and holidays. Each S.O.S. tattoo can display a parent or caregiver’s phone number, making it easier for someone who finds a separated child to get in touch. Customers can also add an extra information line, such as a note about an allergy. The tattoos are waterproof and come in a range of child-friendly designs, combining practical reassurance for adults with something children enjoy wearing.

The brand also offers a “Moedig en Dapper” collection of small illustrated tattoos intended to give children comfort, confidence or encouragement during challenging or exciting moments. These designs do not include a personal phone number. S.O.S. Tattoo provides application instructions and care tips to help tattoos last; depending on skin type and water conditions, they may remain in place for one to five days, including after swimming. The shop sells tattoo sheets online and offers delivery in letterbox parcels, with free shipping when ordering three sheets.
