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

If you follow the directions to the letter the tattoos will stay on for about four hours.  I tried a technique that I had used on other tattoos and the first Piranha fell apart.  Thankfully I had two.  The one my older daughter put on her shoulder stayed there for two days.

I purchased several of these tattoos for a swim birthday party.  Out of the 8 different tattoos, only 2 did not come off within the first 1/2 hour! I wasted $40 on "water proof" tattoos that came off at the slightest rub and in the water!  Only the butterfly and seahorse seemed to be of any quality.
