This disorder is associated with several vascular, neurological, and skeletal problems including stroke, heart attack, clotting, mental retardation, eye abnormalities, and osteoporosis, amongst many other complications.
Tattoo tipping etiquette, in general, should hover around 15% for small tattoos and 20% for larger tattoos, but as with all tips, you as a customer ultimately determine the amount based on the quality of service and the work performed. Consider your involvement as well.
Of course, the size of the tattoo will directly affect the price. Most tattoos start at $50 to $75, no matter how small. This is because the cost of supplies must also go into the price. A tattoo that covers the entire forearm can start around $125 to $300, depending on other factors. In general, be prepared to pay at least $75 for even a small 2 x 2 tattoo. The complexity of the design also directly affects the price.
