It's like having a few containers in one with a movable and removable divider. Great non-toxic alternative to plastic containers. This reusable bento-style lunchbox favorite is the perfect on-the-go solution for sandwiches, salads and cut fruit. Also use for takeout, salad bars, and to store your leftovers in the refrigerator or to bring them to the office the next day. Extreme temperature changes might cause lids to crack. Remove stickers before getting container wet to prevent sticker residue.
