A die-cut "Daichi" name sticker on a steel water bottle, showing a blue oni mask in Japanese irezumi style. The mask has gold eyes, cream horns and black hair, framed by red and pink peonies and navy waves, with the name in black brush lettering on a cream scroll. Swap the name on the scroll, or change the mask colour, flowers or bottle to make your own version.

A product photo of a glossy die-cut vinyl sticker stuck on the side of a brushed stainless-steel water bottle, the bottle filling the square frame with soft daylight and a blurred pale neutral background. The sticker is a Japanese irezumi design cut to a wavy contour, with a thin white vinyl border around the whole shape and a subtle glossy sheen. At the centre sits a fierce blue oni mask, drawn with bold black outlines: deep indigo-blue skin with lighter cobalt highlights and cream bare-paper highlights, two curved ivory horns, furrowed brow, glaring gold eyes with black pupils, a wide snarling mouth with sharp white fangs, and flowing black hair. Large peonies in vermilion red and peony pink with jade-green leaves sit at the lower left and upper right of the mask, with black outlines and petal lines. Curling wind bars in indigo and black sweep behind the mask, with a few stylised waves at the base ending in curled claw-like foam tips, and golden-yellow accents. Flat woodblock-print colour with fine paper grain, no cast shadows inside the artwork. Below the mask, on a cream washi-coloured banner shape that is part of the die-cut, the name "Daichi" is written in upright, slightly condensed East Asian commercial brush-ink lettering: solid black ink, stroke thickness consistent through the body with only a modest taper, clean decisive terminal landings, readable like a sake label or izakaya sign. The name is large, about 60% of the sticker width, centred under the mask. Only that one text string appears on the sticker. Small realistic water droplets on the bottle beside the sticker.
