Dermatographia

This isn't a new tattoo technique, it's a medical condition called Dermatographia which is a condition also known as skin writing. When people who have dermatographia lightly scratch their skin, the scratches redden into a raised wheal similar to hives. These marks usually disappear within 30 minutes. PS: these guys are actually talented, i can not draw a proper line yet they somehow made simple drawings on their skin. :)
