I think these are neat containers. There are three different sizes, one bigger than the next so that you can store one inside another thus saving storage space. There is also a handle on top to hold spoons that came with each container.
I like it that the rim at the top of the container can be removed.
I do not have to pour my bag of sugar into the container. I just slip the whole bag into it...
...and then slip the rim on top of the plastic bag...
...before I put the cover back on.
That means that I do not have to wash the inside of the container when that pack of sugar is used up. I just slip a new packet in.
What a great water and time saving idea.
