A makeshift device constructed using the basic components of a common writing instrument, combined with a small motor and needle, serves as a rudimentary tool for creating skin markings. Typically, the ink cartridge is removed, and the hollow pen casing acts as a tube to guide the reciprocating needle, powered by the attached motor. These devices are often depicted in popular culture associated with prison environments and amateur tattooing.
The accessibility of materials and relative simplicity of construction contribute to the prevalence of this type of improvised tattooing equipment in settings where professional tools are unavailable or prohibited. Historically, such practices highlight resourcefulness in restricted environments and underscore the human desire for self-expression, even with limited means. However, using such devices poses significant health risks due to the lack of sterilization and control, increasing the potential for infections and complications.
