This 2 piece set from Dimayar is nice, compact and still holds enough for a good lunch, snack, small water bottle and maybe fruit.
I was able to use an ice pack, 1 medium square container, one small round container and fruit.
Another day I carried a microwaveable meal and fruit and snack. After lunch I was able to wipe out the lunch bag and fold it into my work handbag.
I also carried a sandwich and fruit another day.
Now keep in mind they are insulated and won’t keep foods hot/cold , still use an ice pack.
Also since it’s a more compact set you won’t fit lots into it.
A great bonus of having 2 is if one gets really messy and can’t be used the next day you always have a back up.
Easy to clean, store and transport.
