I love these divided containers.They have a vent in the lid for letting out steam if you microwave them or put hot food in them.I don't personally use the cover when microwaving the dish, because even being PBA free, well they are still plastic and the heat will degrade the plastic faster.I do put them in the dishwasher. The container can go on the bottom, but I would put the plastic lid on the top rack, I do this mainly to sanitize them.These are the perfect size for a main dish and a side for husband to take to work. He loves them! You can heat your food in them without worrying about any toxins leaching into your food, or food tasting funny. They also clean so well. Much better than plastic that eventually gets so you can't clean it well no matter what.No they don't stack well, but I can stack them 3 high and they are fine.They are so much better than toxic plastic!

High quality. I almost didn't order them because one of the reviews said that the compartments leaked into each other. I don't see any way that could happen. It's molded glass. They are really nice. I love that they are deep, also. The tops are secure. I'm really happy with these. I wanted a set of square high quality containers that were the same size to stack and were also deep so I could quickly see what was in them. These are that! And, they are freezer safe, too. <3

These are absolutely perfect for meal prepping snacks. The glass is nice & thick and the lids are very high quality. Definitely recommend this brand!

The divider doesn’t go all the way to the top, allowing the food in each of the compartments to mix.

These are nice for meals and for snacks. They hold a lot and the glass seems durable. I’ve washed them and the kids in the dishwasher, and they were fine. I wish they had smaller ones of these for small snacks and just for space.

Use these to store meal in appropriate portions after cooking a multi-serving dish. Love quality and compactness of these containers and lids.

If you’re looking for the best containers for meal prepping, these are the ones! The quality of these containers are hands down the best and beats plastic containers any day. I’m very satisfied and would highly recommend these containers to anyone who is looking to meal prep. Well done Meal prepsters!

We love these for every meal
