I've been using these storage containers for a couple years now and they do not stain. I have some in glass and some plastic. The lids are all plastic and fit both materials. The seal is excellent and I can marinate food and flip it over without liquid spilling. They stack neatly in the fridge and the rectangular shape helps avoid wasted space. The lids click lock and have vent holes for heating without removal. This can be good, but also bad. The lid sits inside the rim of the container and you have to make sure not to fill it too much or when you put on the lid the contents will come out of those vent holes. The lids also don't stack as neatly as I'd like in the cabinet, but it's not a dealbreaker. Overall, I would recommend these.

I have purchased several of these containers and have thrown several of them away due to cracks in the material. I emailed Rubbermaid which said they are not to be used for hot liquids but they are microwavable use. I was using these products as meal preps to take for lunches because the liquids stays inside the product with no spillage. After several times of use the bottom of the product ends up cracking. I like the design, how the food stays sealed, how transparent and the capacity of the product but I don't like how the product becomes defective.

This cereal container is very good because my granddaughter opens the box she just rips it so this container is very useful the capacity is just right the plastic is very durable and strong I find it works well plus you can see what cereal is in the container if you have extra cereal containers I have 4 that's how much I like this product

I love these!! Are lightweight, airtight and attractive! I have been using them daily for well over a year. Two cracked- perhaps due to high dishwasher heat. I would love to replace them without the wasting the lids - which are still good. Please make separate pieces available for sale!

I use these Rubbermaid Brilliance storage containers for all my dry ingredients. I'm an amateur home baker and I bake a lot of bread. I also live in a humid climate. I love knowing that my ingredients are going to stay dry and fresh after I open them for a long time! They even stack wonderfully for easy storage. If you bake a lot and always have open paper bags of flour that get flour everywhere, it's time to upgrade to these!

I had to buy more of these. It is the best airtight container on the market. Keeps food fresher with a great seal. I even got some for my friends.

I enjoy buying these sets! They are very nice modern looking! They are very durable, I’ve been using these for over 4 years and if i break or misplace one I always replace it with the same! 10/10

These containers are very useful for storing food. They close tightly and keep everything fresh for a long time. I like that they are clear and easy to stack. Very convenient for everyday use. Highly recommend.

I have three of these for my breakfast cereals and they are amazing! The keep the cereal fresh and holds almost a whole box. It has saved me money by keeping food fresh and crisp to eat.

I just love l9vevth8s cereal keeper. It keeps my cereal crispy and fresh. Once closed properly my cereal stays fresh longer. It hold way more than the small one I use to buy.. easy to clean
