This brand new, Made in Japan, snap top bento container contains 550 ml and has a sturdy look. We love the simple and classic Peanuts artwork on the lid. It would be a perfect container for a small bento or to take some side dish along with you. It is best to hand wash but you can put it in the top rack of the dishwasher. Microwave use is OK but recommended on lower settings for shorter periods of time.
