Question: Can anyone tell me the inner diameter of the container? I want to use it as a mold and would like to know the finished size of my product.
Document: This is advertised as 4 containers (8 pieces including lids)  It is actually 1 container (2 pieces including lids).I see no way to complain to Amazon. No email, no 800 number, nothing. So, this is the only way I know to complain.It is a quality product worth maybe 5 dollars. The jar is made in the US, the lid of course in China.There is no way this product is worth 16 dollars for one unit.
even when they are sealed so as to not leak, they do not inspire total confidence (the way clip and close and kinetic glasslock did)...they just feel like with any nudging the lid seal could be compromised. for example, i would not want to travel with one containing soup if there was any chance at all it could get turned over. they still work for me for all my reasons plus they are too heavy to return cheaply.
I just got this loaf pan sized container yesterday. I can use it so I'm not going to return it. But what I wanted when originally ordering was an object resembling the picture for this item - something low and flat. I doubt that I would have chosen to order this one except for the misleading picture, though if a fuller description had been provided - the actual measurements of the item -  I would have still ordered it.
And providing dimensions on a storage container is pretty basic information to have left out. Capacity is helpful, but isn't nearly as basic as dimensions.The main product information I'd like to add to what has been posted already is that the Anchor-Hocking True Seal food storage sets have a lid that, according to the paperwork that comes with the sets, will work just fine in the microwave (though not in the regular baking oven), as long as you leave the lids loosely ajar.
I really appreciate the shape of this storageware. It helps me make good use of my space in the fridge. I also like that because it is glass it can go right from the fridge and into the microwave.
I purchased these containers to take lunches to work. All of my old containers were polycarbonate with confirmed BPA in them, and I decided to replace them. These seal well (nothing has spilled yet) and are a nice size to take dinner left-overs to the office. As a side benefit, they look nice.Note that I generally only use them for storing leftovers in the refrigerator to eat in the next day or two.
(I don't always pay attention to the text list, as so often it takes up time noting things like "Great Gift Idea!" And even if I did read the text - I think I did this time - I would have chosen a picture to believe over the text, absent the customer comments.)
I got mine 2 days agopros-looks very nice. I was little ify about the light green before ordering, but was happy with the color when i got the box.-the lid is very secure-the lid is microwave safe which is very imp for indian food reheating-not very heavy as compared to the other glass containerscons-color choices for the lid would be a great improvementI have not checked if the lids will lose shape after repeated microwave use or not, that would be the real test
another little bonus is that the sticker comes of very easily after soaking in water for a bit.original review:  maybe 4.5 stars. i didn't purchase these on amazon but this is where i made my purchasing decision so wanted to weigh in here. (bought from organizeit.com because one size -- the one i wanted more of -- was cheaper there.) to everyone who has experienced a leaking problem, you have to "burp" these just like the old tupperware.
I love the product, but the price is ridiculous for one container. The packaging is even marked as being for four containers, but it is only one.
Answer: The top outside measurement is  5/1/2 in.  and the inner measurement inside the bowl is 4 1/2 in.   I hope this helps you out. Good Luck.
