I enjoy using these when sorting business papers. They are durable and hold quite a bit of paperwork. I use this size (1 3/4 inch) for our smaller accounts, and the larger size (3 1/4 inch) for our larger accounts. As I said before they are durable and they hold up well. You can write on them (both on the outside and on the inside.)
Be sure to heck the description and buy the ones that say Manila/Redrope. They are the most durable!!!
These were very hard to find at many places and your rep on the online chat did a good job of finding these for me. They're not exactly what I wanted, but very close, so overall we are quite pleased. Would have liked another color if possible, but that's the only real issue but that couldn't be helped.
