渦巻く波の中を上へ泳ぐ錦鯉を、白地に黒の輪郭線で描いたタトゥー用ステンシル。魚はうろこのある体と、細い筋の入った流れるようなひれと尾、2本の長いひげを持ち、尾の周りには渦巻く波頭と小さな泡がある。魚や水、線の太さを替えたり、うろこやひれを好きな配色で塗ったりして、自分のデザインにできる。

A tattoo stencil of a single koi carp swimming upward, drawn as flat line art in clean black outlines on a pure white background. The koi is seen from slightly above, with its body in a graceful vertical S-curve. The head is at the top, mouth open, with two long flowing barbels, a bold round eye and gill plate lines. The tail rises from the bottom in a wide flowing fan. The body fills about 85% of the canvas height and is centred, with a generous white margin on every side. Large overlapping scales are drawn as closed rounded outlines in neat rows down the body. The pectoral and dorsal fins have long, ribbon-like, flowing rays drawn as open paired lines that join at the fin edges. The tail has long, wavy, translucent-looking lobes outlined with a few flowing interior lines. Around the lower body, a few stylised Japanese wave swirls and two or three curled water ripples frame the movement and lead the eye upward. Every line is a uniform, medium-bold, even-weight black stroke, with rounded ends and all shapes fully closed, continuous and uncluttered. The spaces between lines are wide enough to survive as a tattoo. There is no shading, no hatching, no grey, no gradient, no fills, no solid black areas and no texture, so the artist can add shading later. The result is flat, centred artwork like a printed thermal transfer stencil. No text, no skin, no body parts, no mockup and no background elements.
