This nostalgic, handcrafted bentwood lunch box is made by artisans. The wood absorbs excess moisture from the rice, preserving its flavor, a testament to the wisdom of the past. The cedar wood also has a sterilizing effect, preventing the rice from spoiling. It's a highly functional lunch box throughout the year, as it helps prevent the rice from spoiling in the summer and from hardening in the winter. *Rice may spoil depending on storage conditions.
