Advertisement I don't know the proper name but they are a type of canister that you would put coffee or flour or sugar in. They are really nice and inexpensive--I bought one for coffee for about $5. They have a good sturdy seal on them thanks to the silicone lining on the lid. This is the first time I've looked at this thread and I am LOVING it!!!! I wish we had a heart smilie!!! I'll settle for :clap: !
