"Luck" is a die-cut koi sticker in Japanese irezumi style, shown on a laptop lid. A red-and-white koi leaps through indigo waves beside a pink peony and red maple leaves, with "Luck" in black brush lettering beneath the tail. Swap the word, the koi colours or the flowers to remake it as your own sticker.

Product mockup photograph, square frame: a single die-cut vinyl sticker stuck flat on the lid of a closed silver aluminium laptop, seen from slightly above, soft daylight, a gentle glossy sheen on the vinyl and a faint contact shadow beneath the sticker. The sticker has a thick, even, clean white border, about 6% of the sticker width, following the outer silhouette of the artwork in smooth rounded curves. It fills about 70% of the frame, centred, slightly tilted by 4 degrees. Artwork in the Japanese irezumi woodblock style: a large koi swimming in a diagonal S-curve, its head rising at the upper right. The koi is red and white. Vermilion red patches sit on cream-white scales, drawn with bold black outlines, with each scale as a neat curved line and flowing translucent fins and tail edged in black. Deep indigo waves curl around the lower half of the koi, with claw-like white foam tips and fine cream swirl lines. A few curling wind bars in graded black-blue sit behind the fish. One pink peony and two small falling vermilion maple leaves are tucked at the edges. The background inside the sticker is plain cream washi paper with subtle woodblock grain, evenly lit, with no glow. Across the lower third, over the calm cream and wave area, the word "Luck" is painted in classical Japanese shodo brush lettering: dense sumi black strokes with a bold 5:1 thick-to-thin ratio, a gradual loaded-brush entry, a tapering harai exit and an upward hane flick on the k, with slight dry-brush texture only at the outer edges and generous spacing. It is upright and authoritative, and reads clearly at about 45% of the sticker width. Colours: vermilion red, indigo blue, cream white, sumi black, with small accents of jade green and peony pink. The laptop lid is a clean, uncluttered, blurred grey metal surface, with no other stickers and no other text.
