The handles on these boxes make them easy to lift. Even though they are listed as economy they are sturdy enough to fill with books and are still in good enough shape to reuse several times.
Have purchased these in the past - mainly used for annual receipts and income tax materials. They store nicely and keep the paperwork well. I purchased the latest group to temporarily store file cabinet material. We are changing the floors in our home and need to facilitate moving all of the furniture around. The file cabinet was too heavy as is so we removed all the paper and stored in these boxes. They work well even with the sliding folders. This effort allowed us to lighten the load.
Our company has been using these boxes for the last 14 years. The boxes are very durable to the point where we have been recycling over and over again. The size is perfect for either legal or letter size documents. They are very easy to assemble and easy to take apart and save for later use. They store perfectly and makes it very easy to save space especially when you have limited space to store. I strongly recommend this product not only for business use but these are great for personal use and when moving too!
