Un par de diseños flash de tatuaje de línea fina: un candado y una llave antigua, dibujados con contornos negros limpios sobre papel blanco roto. El candado tiene un ojo de cerradura y tres pequeñas líneas de destello, y la llave con anilla tiene las suyas, con un trazo fino y uniforme en todo el dibujo. Cambia los objetos, el grosor de la línea o el color de la tinta, o elige tu propia ubicación.

A tattoo stencil reference sheet on plain warm white paper showing a matching pair of small fine-line tattoo designs for the sides of fingers, set side by side with wide empty space between and around them. Left: a small padlock in clean black outline, a rounded rectangular body with a curved shackle on top and a keyhole made of a small circle with a short tapered slot. Right: a small antique key in clean black outline, with an open round bow containing a tiny inner circle, a straight slim shaft, and a bit with two square notches at the end. Both are drawn upright, long and narrow so they fit the side of a finger, and are about the same height. The lock has a small hairline spark of three tiny dashes at its upper right and the key has the same three dashes at its lower left, so the two read as a set. Use one uniform thin-to-medium black line weight, round line ends, no shading, no fill, no hatching, no gradient, no drop shadow, no text, and no hearts. Every gap between lines is open and generous enough to survive on skin. Soft even lighting, flat and graphic, with no hands or skin shown.
