I bought two packs of (4) Hanging File Pocket 3 1/2" Expansion Letter Size to use in my old fashioned hanging file for regular folders that have grown too full but are not candidates for shredding or elimination as yet. These are nicely expandable and fit the same as regular width hanging file pockets for folders. I purchased them using my $10 coupon off for bringing in my old laptop and mouse for recycling. Thanks Staples!
They work great for my choir music folders. Instead of having to label 2 or 3 Manila folders and a pendaflex folder to hold them. I usually need only one Staples Hanging File Pocket folder to file 45 plus pieces of choir sheet music. Saves so much time. Good product.
