I use paint pens to draw designs on hands, face, basically anywhere. Price would depend on size of design. My designs are primarily henna patterns, but I also do geometric designs, and seasonal themed doodles. (ex. Halloween: bats, ghosts, spider webs, etc.)
The paint generally lasts about a day, the main factor that would determine the duration the paint would stay is the location on the body. Paint can last as long as 3 days if taken care of. Paint on face is harder to get off, tends to stay longer, and in some individuals may potentially irratate skin (rare).
I use "Painters" acrylic paint pens, colors; red, blue, black, white, red, gold, and silver.
I can do birthdays, festivals, parties, etc. If you are looking for someone that does body painting with original designs I'm your guy. ;)
