Question: Are you supposed to leave the clear circle plastic seal things in the canisters?
Document: Looked every where for a set of canisters that were not just plastic or clear material. These look great on my daughters counter (a Christmas gift for her). There were also matching items available so bought the utensil holder too.
Glad I got these, as they go very well with the rest of my generally red kitchen. They're sturdy, robust jars, good ceramic. The plastic seal on one of the lids doesn't quite fit right, though, and tends to fall off sometimes when we're opening the jars. This leads me to question the overall quality of the seal, but so far, I haven't had any moisture problems.
I really like these, I ordered them in red. The color in the picture is very true to life. I am very happy with them. The only not so good thing is the rubber seal on the lids. I personally am using them for decoration and to put miscellaneous things inside them, I wouldn't put sugar or flour in them because the rubber seals are not that great, I actually removed them so I can open and close them easier.
I must say I LOVE this product. The pieces are heavy with a top quality look to them. The lids have a plastic seal for tighter closure. The red color is definitely burgundy not the red-orange so I would suggest buyers to coordinate accessories from the same line of Sorrento to match these reds. I bought the spoon rest from this set and equally love it as well. Well designed pottery!
The canisters are just lovely....a perfect shade of red for me. If you want candy apple red or fire engine red, these are not for you. The lids do give an airtight fit and will undoubtedly keep things fresh. My only complaint is that they are a bit smaller than I had hoped for and don't fit a lot in them.
These are beautiful canisters and look great in my kitchen. They are heavy and seem very durable. However, the plastic rings that are used as the seals became such a problem that we finally removed them and will take our chances with moisture creeping in. The rings kept flipping up or otherwise moving out of place when we opened or closed the lids and then the lids not only weren't sealed, but askew.
This set of three ivory canisters arrived just a few days after ordering. They came SO well packaged that nothing COULD have broken! The canisters themselves, are ivory and each with a slightly different design/marking that makes them appear antiquey -- Just the right size for my kitchen (albeit they would NOT hold 5#'s of sugar/flour) which is fine as they DO have a plastic ring around the lid making them air-tight.
Well, these are what they are... cannisters with lids for storing things.
I really like these. They have a plastic rim that seals the lids they are a little smaller than what I had hoped.
We love these for our kitchen. They blend in nicely with our red electric appliances. A must have if you like color. I also bought the bread, cookie jar. Looks great and keeps things fresh.
Answer: I did not remove the seal around each lid.  It keeps the canister more air tight.  In fact, I think the seals in these canisters work better than some of the others I have had.  The sugar hasn't clumped even in all the high humidity we have had this year.  I am very pleased with this set.  Just to be on the safe side, while I wash the body of the canisters in the dishwasher, I do hand wash the lids.
