Weck Jars. Marvin’s Number 1 pet peeve is tupperware. He hates that the lids and the containers don’t elegant fit and there’s always a spill of them somewhere. In general, he hates plastic. So, these Weck jars are awesome because all the lids fit all the bottoms of different sizes. It’s a one-lid system (unless you get the itty bitty ones but I’m talking about the ones for leftover food storage not sauce storage). I really like this half liter size because whenever someone would drop off food for a Meal Train, I would divide everything up into five of these jars and have them ready to go to throw into the microwave when I woke up to pump. They’re see-through so it’s easy to see what you have in the fridge and what to rotate out when it’s gone bad. #susansfav
