We love the twist-off lid feature on this two-compartment Rilakkuma bento case. This is brand NEW from 2018 and would be a wonderful collectible or handy lunch box. Once you open up the lid you find a small tray with white lid that you can pack your rice in. The unit measures about 10 x11 cm (approx. 4"x4.25") What a nice little bento box to take to work, school, or a picnic.
