These pricey meal prep containers from @katy. They’re dark grey/black and $20 for 4, but omg I deadass love them. The container is a really thick plastic and dark so it won’t stain or at least show the stain. I put them through a beating and they last. Plus it’s a deep set container so my more saucy stuff works. Additionally, the lid is fairly solid and has a vent you can pop up.

Edit: it’s from amazon and on her list if she still has it. I’ve had then for near 2 years now IIRC and they still look new with tons of microwaving.

Edit2: Found it here

Yep! Found it here
