Have several ,love them,Never got one germ of any disease.I still think the stereotype urban legend dogma that surrounds tats ,those who get them ,how unsafe they are is ignorant at best.: This is not the free wheeling 70's-80's laws and resrtictioins have come a long way.Dont expect much from the guy down the street in the alley who will do a nice tat for $50 bux!
Any reputable shop will have disposable needles,for each persons(clients) use and autoclave machines for the hard parts( tat guns etc etc )
