Niwaki Bento Box

No, this bento box is neither microwave nor dishwasher safe. Due to the anodized aluminum construction, it should be hand-washed with mild soap to maintain its finish and integrity.

The box comes with a dedicated elastic strap that wraps around the exterior to keep the lid firmly in place. While it provides a secure closure for standard commuting, it is not leak-proof, so it is best suited for solid foods rather than liquids or soups.

The internal plastic lid acts as an additional layer of protection to help keep your food contained and organized. It sits inside the aluminum shell to prevent ingredients from shifting or mixing during transit.

The box is crafted from high-quality anodized aluminum, which is designed to be durable and resistant to corrosion. It does not impart a metallic taste to food, making it an excellent, long-lasting choice for daily meal prep.

With dimensions of 150 mm x 105 mm, this box is sized for a single, refined portion. It is ideal for traditional Japanese-style lunches or light, balanced meals that fit comfortably within its compact oval footprint.
