Tattoo flash is any tattoo design that is pre-prepared for customers to avoid the need for custom designs, or as a starting point for custom work. Tattoo flash was designed for rapid tattooing and used in "street shops"—tattoo shops that handle a large volume of standardized tattoos for walk-in customers.[1]: 111 Pieces of flash are traditionally drawn or printed on paper, and displayed for walk-in customers in binders or on the walls of tattoo shops. In the 21st century they may also be advertised online and on social media.
