Review (4/5): They'll do
The first picture is when I first put this on my leg, three days ago. The second picture is now. It has been through multiple hot showers, and even a hot bath, although not scrubbed. I would say is kept in tact pretty well. Though most people will probably put it on their mouths and want to remove it later on that night.
These are a pretty good size for the mouth and won't take up your whole face. The details are kind of washed out. These look more abstract than really realistic. This one looked like it had lighter spots and more contrast, but when I put it on it just looked all red. These have no hole for your mouth, so you will have to make one. Overall, I think these are great for Halloween.
