A sleeve tattoo is a large tattoo that covers most of the arm. It’s a type of body art that can range from a simple geometric design to a complex, detailed art piece. Sleeve tattoos generally start at the shoulder and extend down to the wrist. They can take up a lot of space on the arm and can be expensive, time-consuming and painful. But the results can be worth it. A sleeve tattoo is the perfect way to show off your personality and make a statement.
