The Paper Bombs are small, rectangular sheets of paper with intricate sealing formulas written in bold, black ink, glowing faintly with a blue hue. Each sheet is meticulously folded into origami shapes, primarily resembling shurikens or butterflies, with sharp, precise edges. The paper has a slightly weathered texture, indicating frequent use, and the edges may show minor singeing from previous explosions. The design is minimalist yet highly detailed, with the sealing formulas adding an ornate touch to the otherwise simple paper material.
