I HAVE AN INCOME TAX BUSINESS AND USE THESE BOXES TO STORE PAST YEARS FILES. WE KEEP 5 YEARS WORTH. WHEN WE SHRED THE OLDEST FILES WE CAN USE THE BOXES OVER AGAIN.
I use these for sorting when working on an organizing project (home office kitchen bathroom garage workbench hobby supplies etc.) Good for longterm storage of paperwork. Not good when concerned about dampness or heavier items - then use plastic bins. Keep a supply on hand. You'll never know when a good box with built in handles will come in "handy".
Exceptional for household storage of all sorts of objects other than files. An unbeatable price compared to plastic or wicker and therefore a helpful segue between initial organization efforts and a more aesthetic solution. Ease of labeling ease of access and ease of stacking make these a beautiful choice for all sorts of clutter defying endeavors.
