I like to use these boxes for moving. They are small enough that if you fill them with books you can still pick them up. These boxes don't require tape to put them together. They break down so you can use them over and over. The uniform size makes stacking and loading your truck trailer or car easier.
The boxes are used to store prior year tax returns. These boxes weigh too much when full. They are too long and not easy to handle because of their length.
