Tattoo flash is a form of artwork that is typically used to create tattoo designs. Traditionally, tattoo flash was used by tattoo artists to copy or create their own designs to use on clients. It was usually either a drawing or a painting and was displayed in a portfolio in the tattoo shop. Today, tattoo flash is still used to create tattoos, but they are also used to decorate homes, offices, and other spaces. Tattoo flash is a great way to express yourself and to show off your individual style.
