Two large wound tattoos or gashes you can put next to the mouth on either side. They make it look like you’ve been cut and your mouth is now very wide. There are also four small cuts to use on the face under the eyes or wherever you need them. If you apply some coagulated blood and some dripping blood to them, they look almost real.
These are tattoos, they are easy to use and very effective looking.
You don’t need glue of any kind to apply them, just water.
