The Long Spark is a slender, elongated firework designed in the style of feudal Japan, featuring a bamboo shaft wrapped in dark red paper with gold kanji inscriptions. The tip is conical, made of a slightly rough, matte black material that contrasts with the glossy, vibrant red and gold body. A thin, braided fuse extends from the base, hinting at its explosive nature. The overall design is sleek and elegant, with subtle weathering to suggest it's been carried in a warrior's pack.
