My fridge is perpetually fucked, but this dumb analog tool has made a HUGE difference

I'm busy and scatterbrained, and my husband and teenager will squirrel stuff away and totally lose track of it so they're either leaving things in there perpetually, or thinking "Yeah this deli meat is only a few days old, I'll eat it!" when it's actually weeks old!

We've been wasting so much food, not taking advantage of easy meals we could eat using leftovers, and stuffing the fridge full of mystery tubs that then have to be decluttered / de-molded.

This list is actually keeping the fridge manageable, my grocery bill smaller, my cooking effort lower, and protecting my family from food poisoning!
