Silicone Baran Food Separator Bento Box Accessory Cherry Blossoms Sakura | eBay
These are really cute bento baran (food dividers) for bento box lunches! These are made of silicone and therefore can be used over and over!
These can used in the microwave, fridge and freezer.
DO NOT use in the oven.
It says they can be washed in the dishwasher but please understand that Japanese dishwashers are different than those in North America so I would wash by hand.
