Did I mention the new invisible edible ink used in this gun ? You can spray it all over the place and it can be either wiped or licked off without any mess or damage to the artwork.
You can use mine free of charge, whenever you need baby...
I think I have a special type of tattoo gun designed just for that part of the body. It virtually pain free for me to administer to you, requiring only a sufficient amount of spit to lubricate it up to a safe hammering speed.
