I purchased the piranha tattoos for our 12 year old girls soccer team to use during a weekend tournament...our girls play like piranhas so I thought it would be a good motivator for them. I assumed that if people swim with these tattoos and I was told they would last through 3 days of pool usage they would last 3 days for outdoor use.....what is said about assume!!! DON'T ASSUME!...The tattoos were faded and/or gone after 30 minutes of soccer...well that was a quick $60...if they would of only lasted 1 day for 2 games I would have been happy
