These are not as sturdy as your large bins, but they are of better use for lighter things. I use them to store my specialty paper and also my paper scraps. These are also good to keep a project you are working on all in one place, especially cards.
These styfftainers are perfect for those little ink cubes. I put that no slide stuff on the bottom and my Memento Dew Drops fit perfect.
This is the first company that took time to really ship them well protected. They arrived in perfect condition and I was very pleased.
