■ Brand/Model: Ohba Seihou (OHBA) - A top-tier Japanese brand favored by the Imperial Family. This is a soft business bag made of shrink leather. It appears to be an early model, different from current ones. ■ Maintenance and Condition: The following maintenance has been performed for long-term use: Full interior lining replacement: The inner fabric has been replaced. Lock component replacement: The central lock unit has been replaced with parts from the long-established manufacturer **"HINOMOTO Lock"**. *The key for the lock is not included.* Corner reinforcement: Reinforcement has been applied to the corners from the sides to the bottom.
