Here's an excerpt from the explanation at a Wakasa-nuri chopsticks specialty store regarding the decoration: By scattering seashells and eggshells, then repeatedly applying and polishing layers of lacquer, these patterns emerge. One of the charms is how the colors change depending on the viewing angle. Regarding the condition: The box is not in very good condition due to long-term storage. The chopsticks themselves have been visually inspected, but this is a layman's inspection. Please consider age-related deterioration when making your purchase.
