◆ CONDITION

Nearly unused set in excellent condition. No chips or damage found on any stones. White Hamaguri stones are clean with natural grain visible — a hallmark of authentic Hyuga clamshell. Black Nachiguro stones are smooth and uniform. The original storage box shows age-related wear and surface soiling on the exterior, consistent with long-term storage, but the stones inside have been very well preserved.
