HOW TO APPLY THEM
According to Flashtat.com, which also stocks the tattoos, for best application, ask a friend to help position your tattoo so your skin does not twist or stretch.
You want to make sure your skin is clean, dry and free of any oils .
Cut out the tattoo as close to the edge as possible (this is important later when you need to line it up) and remove the clear sheet.
Place the tattoo face down on your skin and hold a wet cloth against it for about 30 seconds.
Peel the paper aside, then pat gently with the wet cloth.
Be sure not to twist or stretch skin until the tattoo has had time to set (at least 10 minutes).
The tattoos look best after they have had an hour or two to set into the skin. – Flashtat.com
