What to know before buying

Listing details to confirm

Capacity is listed as up to 100 sheets. Actual fit may depend on paper thickness and any folders stored inside. The listing also gives an unexplained capacity value of 16 ounces, and its sheet-size field is formatted inconsistently as "8.5-x-11-inch inches" despite separately specifying Letter (8.5 x 11 inches). Confirm the intended capacity and paper format if these details are critical.

Who is it for?

A good fit for

Students, teachers, or office users sorting Letter-size documents into several color-coded groups.
People who want pockets for loose notes alongside three-hole-punched pages.

Less suited to

People needing a binder for a large document set beyond the stated 100-sheet capacity.
Anyone who needs a specified pocket layout beyond the listing's count of two interior pockets.
