  • Rated 5 out of 5 by from Works perfectly! Great OXO quality and design. No issues with the lid but it needs to be set on properly to close.

    Rated 2 out of 5 by from Flap broke first time I used it. I used one of these with great difficulty in getting the flaps to lock in place. The smaller size flap broke the first time I used it. Very disappointed in this purchase.

    Rated 5 out of 5 by from Love the secure lid! I use this container for salsa and it's the perfect size! The locking lid keeps my salsa from leaking everywhere [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Great for Freshness and Beauty I was initially impressed with the container for the thickness of the glass and gasket to keep my food fresh. I was also able to put it in my dishwasher which is great when you work full time and need to save time wherever you can. I remained impressed when I sliced up my strawberries over the weekend and by Wednesday they were still as fresh. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Easy snap lid I love the design of the lid. I have some in a similar style and the lid was always very difficult to snap on and never seemed to lock tightly. This has a smooth snap mechanism. I’m slowly switching to all glass storage and this line is awesome. [This review was collected as part of a promotion.]

    Rated 4 out of 5 by from Manages to Make Leftovers Appealing I received this glass container a few weeks ago and it has been in constant fridge rotation ever since. The quality of the product was obvious straight from the box. The glass is thick and seems like it could handle a fall without shattering. The cover gives a satisfying snap ensuring leftovers are protected. Another plus of this lid is that you can almost overflow the container and still get a tight seal every time. I have stored everything from leftover roasted chicken to cookie dough and never worry that the lid might pop off. This lockability makes it perfect for transporting lunches without leaks, though it adds considerable weight to my lunch box. I love that it can goes in the freezer, fridge, microwave, and oven, making it perfect for any type of food storage job. My only disappointment is that the product arrived slightly damaged (see photo) with a chip on the corner of the lid. This hasn't in any way interfered with its function and is just a cosmetic issue. I am eager to build my collection of these containers in the future! [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Love the glass Love that this is glass so I can always see what’s inside! Got the glass because I knew it wouldn’t stain and for sure doesn’t. Also no leaks and so versatile, fridge, freezer, dishwasher, and microwave!! [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Great Container! I love this storage container. It is made of glass which makes cleaning it simple and easy. The glass doesn't hold on to food odors which is amazing. I love the easy snap closure lids. [This review was collected as part of a promotion.]
