Three of four appeared used
Three of the items in the four pack appeared to be used. One had a broken corner but is still usable. I’m keeping them because they aren’t dirty and I can wash them but I would expect better. If you want to sell used stuff, the price should reflect it!

Shipping left somewhere else
I am writing to escalate a serious concern regarding a recent delivery. I ordered a heavy package and specifically chose delivery due to health reasons—I am unable to carry heavy items up the stairs. I live on the third floor, and the package was left on the first floor, which is both unacceptable and unsafe. Not only was the package not brought to my door as expected, but it has now gone missing. Leaving a heavy package in a public area where anyone can take it defeats the purpose of home delivery and puts customers at risk—especially those of us with health concerns. This is extremely frustrating and disappointing. I chose Target for the convenience and reliability of your delivery services, and I did not receive that.

Great seal!
[This review was collected as part of a promotion.] Using this to freeze sauce and it works great! Perfect seal and very sturdy.

Great quality
These Tupperware are a little expensive; however, they’re really nice quality! They’re very durable, wash well, seal well, and I love that they’re color coded. I ordered the larger orange ones, as well. I would definitely recommend these. Very happy!!

Great bowls
Love these snap tight lids. The bowls are microwave safe and dishwasher safe. The vent hole on the snap lids is also nice. Would highly recommend.

A favorite for all seasons and reasons
First the square shape of this container is ideal for most items that I seek to keep cold. Its square shape provides maximum utilization of space and is very stackable. It's sealing ability for my many months of using has maintained it's integrity, despite multiple cycles. It is durable, in as much as I have not experienced cracking. It does not appear to absorb foodstuff, causing color changes. I have yet to use it for frozen produce, however, will start to explore that area. Currently, I vacuum pack long term storage items to expel air. These containers I am considering using for short term frozen food storage in which I will only utilize a portion of the container's content at the time. The content of the container is clearly visible on all sides of the container. Based upon my many, many years of experience of using Sterilite containers I expect these new products to be used by me for many years to come. I have also found them useful for dry, unrefrigerated storage aboard my sailboat, for snacks, spices, first aid, and other items to be protected from the salty, humid conditions.

Great container for kids lunches!
This is a great sandwich container for kids lunches. We a have 3 kids and 6 of these containers. They wash up great in the dishwasher too! Recommend them to anyone who packs lunches for school or work.

Size is perfect!
This is the perfect size for your lunch/dinner, throw in your bag as you leave for work, school, or wherever you are headed for the day and not worry about it leaking. We have several just so everyone in my family has no excuses as to why they can't take leftovers for lunch and warm up at school/work. Plus, no more smashed sandwiches as this container is the perfect size and sturdy!

Fantastic....just wish they offered replacement lids.
We have a set of these in multiple sizes. They have worked wonderfully and have typically been my go to storage choice. However, the flaps on the lids have begun to break off. We've had them for about 3 years now....and they've been used fairly regularly. I inquired about ordering replacement lids as one of the primary reasons I use this type of food storage containers is to avoid consuming and throwing away plastic...however, I was told they do not sell replacement lids. I think that's a huge mistake on their part. The design of the lids almost guarantees they will break one day and it makes total sense to provide replacements....disappointing!

perfect for lunches!
My son has cerebral palsy and needed something that would be easy to open for his lunch sandwiches. These have been perfect! We have been using them nearly every day for several years and they are still holding up fine. I purchased similar ones made by Snap-Tite and they did "snap", into pieces and had to be thrown out. Now I will only buy Sterilite. I have all different sizes of these and use them for everything.

Love the color coded lids
I like being able to open the cupboard and see the container/lid at a glance.
