The Explosive Note is a small, rectangular piece of paper with intricate sealing symbols drawn in bold, black ink, typical of the Fuinjutsu style in the Naruto universe. The paper has a slightly weathered look, with edges that appear slightly burnt or singed, hinting at its explosive nature. The center of the note features a prominent, glowing red seal that pulses faintly, indicating its charged state. The overall design is simple yet effective, with the paper having a matte finish and the ink appearing slightly raised, giving it a subtle texture.
