Very useful labels.
I bought some plain photo boxes (look like shoe boxes) to put each year's papers in so I can find them if needed. I can use chalk to write the year on the label and once their retention period has ended, I can re-use the box by just erasing the year and writing in the new one. The fun shapes will make them look interesting on the shelf. There are plenty of extras which I may use on my canisters and ArtBin super satchels where I keep lots of craft supplies.
