I purchased this for 8250 yen the other day, but the size didn't fit, so I'm putting it up for sale. This is a bentwood lunch box, a small oval type, made by Shoichi Kusakari in Chizu Town, Tottori Prefecture, using Chizu cedar. Capacity: Approximately 700cc Material: Cedar (Chizu cedar) Unpainted, natural wood finish Size: 15cm x H approx. 6cm Round bentwood lunch box ~What is Bentwood?~ It is a box-shaped or cylindrical wooden product made by bending thin boards of cedar or cypress. It has advantages such as keeping rice fluffy and delicious even after a long time due to the moisture-absorbing effect of natural wood, and making it less prone to spoilage. ~Caring for Bentwood (Natural Wood Finish)~ ・Do not use detergent; wash thoroughly with hot water using an acrylic scrub brush or similar. Do not use a dishwasher. ・After washing, dry thoroughly 【with the inside facing up】. ・Do not use a microwave. ・Before packing rice, wetting it with water will prevent the rice from sticking. ・The corners may turn black over time. This is not mold, so please don't worry. Kuriya Keishin Shibata Store Odate
