Bought these and another set of glass storage jar food containers to replace all the plastic food storage containers that go in the fridge and freezer. (All but the two plastic sandwich containers you see in the photos. Those are so my kid can take a sandwich to school for lunch and not have the weight of the glass container weighing down an already heavy backpack...) I prefer glass storage containers as they can not only handle the fridge and freezer well, but the microwave, too. This way, by having everything glass, I don't have to worry about people in the family forgetting that plastic containers should NOT be used in the microwave for reheating food! The lids snap on pretty easily. Sometimes when I snap on a lid, they won't click on one side, but if I unsnap it, rotate it 45 degrees and try to click it closed again, it goes on without a problem. This really isn't a big deal though I know someone posted about that for one of these sets. I keep these and the others with their respective lids attached to their bottoms so I don't have to play "match-up" later. A few of the containers between the two sets look similar so it might be easy to mistake a lid for one for the other. I try to make sure all the moisture is gone from in-between the lids and their rubber seals so when closed in the cupboard, they don't build up condensation. I haven't used them in the regular oven, but they suit our needs and this particular set comes with enough different sizes to cover all the food prep and leftover basics.

air tight microwave safe love them dishwasher safe as well

Fantastic set for various sizes and projects. Have used for my diabetes supplies, food, and whatever else. Highly recommend this set to everyone and especially handicapped ppl

I’m really satisfied with this product and thank God nothing was broke when I got it. We’ll see how it holds up.
