I do really think that this small size is really portable and good for sandwiches and other small snacks on the go. It's not a typical Tupperware that I have in my cabinet but really convenient to have due to it shape and size. Again, this Tupperware is not very hardy, and only works as a beginner set and the top on this one is equally as hard to put on and pull off as the others.
I love these for my sons sandwiches. I don't have to worry about them getting squished in his backpack. These are durable and the lids fit nice and tightly. They are lightweight and easy to fit in his lunch box. They are easy to clean, whether doing it by hand or dishwasher. I can pack multiple things and they stack on top of each other making storage a breeze.
Love how these come in a variety of sizes to choose from. They're stackable which is perfect for storing. Another thing I love about these specific containers is that the lid fits two different sizes. The quality isn't bad but isn't great either. I filled the container half way and flipped it over to see if the lid popped off, it didn't but still leaked very little. When filled all the way, the lid still doesn't come off but the leak is heavier. I'd squeezed too hard, the container cracks. They do clean easily but just like other plastic Tupperware, they can stain.
These are such a practical little set for everyday use. The size is perfect for snacks, sauces, or small leftovers - I've been using them a lot for quick toddler portions and they come in really handy. I like that they stack nicely, so they don't clutter my cabinets, and the design is simple but functional. The lids snap on pretty well for fridge storage and I haven't had any leaks so far with thicker foods (like yogurt or dips).
This Tupperware is excellent! I used it to pack a sandwich for lunch but it could easily hold pasta, salads or other dishes! This set comes with 5 containers! That's a steal for the price. They are easily sealed and stackable. I wash them on the top rack of my dishwasher and they have yet to warp or stained. The color is a vibrant blue which I think is perfect. I would definitely recommend these to anyone looking to replace their current set!
These are a nice size for the leftovers we have at our house. They are a little hard to close, but it may be since they are new. The color looks good, and they can be stacked. The plastic is thick for the price of these. Overall they are good bowls.
The Pros Perfect Size: these are the perfect size for a sandwich or a little bit of leftovers. Value: Since they come in a 5-pack, it's not a huge loss if one gets misplaced or sent to school and doesn't come home. Storage Efficiency: They stack beautifully in the pantry or fridge, which helps keep things organized. BPA-Free: It's a relief that they are safe for food contact without harsh chemicals. The Cons Durability: The plastic is on the thinner side. They can become brittle over time, especially if they are frequently frozen or put in the bottom rack of the dishwasher. Staining: If you use them for tomato-based sauces or chili, the plastic tends to stain and hold onto that orange tint. Seal Quality: While they "snap" shut, they aren't always 100% leak-proof for thin liquids like vinaigrettes if they get tossed around in a bag. Final Verdict These are excellent for dry snacks, meal prep portions, or craft supplies (like beads or small hardware). However, if you're looking for something to hold soup in a lunchbox, you might want to double-check the seal first. For the price, they are a solid household staple.
These are made of thick and sturdy material. Good size for meal prepping something for work, or school. Small enough to have room for other things in your lunch box. Or can use for leftovers in the fridge. Stackable, and has a great seal with the lid.
Mainstays 5-Pack Round Containers I've been using the Mainstays 5-pack round containers for a while now, and they've proven to be incredibly convenient for everyday use. The size is just right for snacks, leftovers, or small meal prep portions. They're lightweight yet feel durable enough to reuse multiple times without any issues. One of the features I appreciate most is how easily they stack in the fridge, which saves valuable space. The lids fit securely, giving me peace of mind that there won't be any spills. Cleaning them is hassle-free as well, whether I wash them by hand or pop them in the dishwasher. Overall, these containers are a great budget-friendly option for staying organized in the kitchen. They're definitely a practical and useful staple to keep on hand!
These are nice food storage containers. They are a good value for what you pay for them. They're on the lightweight side but still pretty durable. They're great for leftovers or packing lunches. I haven't noticed any discoloration yet. The lid has a tab to make opening them easier, which is a neat design.
