There are some concerns recently about the spread of disease (especially
Hepatitis-B and AIDS [HIV])
To consider whether a clean environment you been tattooed?
Are needles used for tattooing reused on other customers? If so you should avoid tattoos in these places
Because the spread of the disease in the activities of the tattoo depends on the cleanliness and needles used
Make sure they use needles only for single-use
And in case you should also consider the Hepatitis-B immunization
So better safe than not..
