Source One 4x9 Inch Tri-Fold Brochure Holders with Business Card Slot - 40 Pack Red - Perfect for Trade Shows, Retail Displays & Office Reception Areas

So far it's survived a few tumbles from a table onto a parking lot pavement. I fully expected it to be cracked when I retrieved it, but it's held up so far. It works great for my son's business cards and brochures he put together for selling at flea markets, etc. I'm down one star on durability, only because we haven't used it that long.
