Bentology Bento Box 4 "Bentology Box" 07 July 2017 I bought two of these boxes recently and used them for the first time today. The lids are a little hard to get on but are secure and didn't leak. The box holds a good amount of food. My only complaints would be that the lid doesn't fasten great and feels like it could pop open. I will most likely buy a bento box elastic for extra security in future. It would have been good if it came with cutlery as not all fit.
