I gave these a 3 rating because I also didn’t read the specifications well enough before ordering. These are NOT air tight seal so product shelve life will decline. They are very cute and aesthetically pleasing on the counter top but they are very small. The smallest packaging of flour doesn’t even fit in the 2nd to the largest. I was very disappointed in this purchase but again make sure you read the information and specifications closely to make sure these will work for you.
