DCs sistema bento lunch box won't fit in their lunch cool bag thing, any ideas?

[Wrybread]

Just bought these fab bento lunch boxes for the dc but they won't fit in normal sized lunch bags that we have. Just a tiny bit too big. Any one else had this and found something that works? Or have ideas for slightly bigger lunch bags?

Slightly bigger neoprene bag.

Brilliant, thank you
