Over 100 years and going strong, Aladdin continues to break new ground with award winning designs, innovative material and eco-friendly solutions for the everyday. The BENTO collection is inspired by Japanese bento boxes; the unique stackable containers can be adapted for any recipe while food is stored at just the right temperature. The 0.60L Bento box keeps food hot/cold for up to 5 hour, within the lunch box is an internal divider to keep food seperate. The 100% leakproof lid has a silicon vent that prevents vacuum building inside the container. The Bento box can be microwaved without the lid.
