For what occasion can you give out tattoos ?
For a birthday party, applying fake tattoos can be an activity for little and big ones, but you could also give them out as a souvenir or put them into a pinata or party bag, with sweets and other little gifts. There are some for a hen party too, it could act as an activity to do together or as a surprise for someone. For a wedding, tattoos could instead be available at a "tattoo bar".
How long do the tattoos last and how do they come off ?
The tattoos are temporary and their durability can be varied. They can last for just a few hours with audacious children at a birthday party or a few days with more careful adults. To take them off, soap and water are often enough, but feel free to use a wet flannel to scrub it off if you need to.
