I've used these for a while
Fitpacker Meal Prep Containers... https://www.amazon.com/dp/B00VWJHFTM?ref=ppx_pop_mob_ap_share
I can say that we (SO and I) bought Fitpackers and they have lasted us an entire year. Together we use about 8-10 packs a week. Some of them are a little beat up but for the most part they have lasted excellently!
What about these puppies?
I'm a fan of fitpackers (https://www.amazon.com/Fitpacker-Meal-Prep-Containers-Compartment/dp/B00VWJHFTM). I've dropped one when it was full of soup and nothing spilled, cracked, etc.
Sure, here you go. No, they aren't Igluu but there are plenty of good brands out there. Enjoy your new containers!! There is something satisfying about having a stack of lunches prepped in matching containers.

I bought the plastic ones 3 years ago and I think I've recycled about 1/3 of them by now because the sides broke. But that's just normal wear and tear - they are pretty good basic containers for the price. There are definitely better containers out there though - I don't think I wanted to pay that much because I was just starting to meal prep and didn't know if I would stick with it, but now I would probably buy some higher quality ones.
The glass ones are higher quality but they don't stack like the other ones. Depending on your storage situation and how many you want, that may or may not bother you.
