EncinoMom’s All American Camp Store:
Tupperware Lunch ‘n Things Container
Similar to the one I used in this video: https://youtu.be/qbj_KWnN16c (at 2:04). Mine has a white lid, dark blue bottom and is several years old. Handy for camping, pic-nics and left overs from your veggie tray, the divided sections are just right for packing individual meals.
