Business Source 09951BD Binder .50" Letter White 4 Pack

0.50-Inch Round-Ring Binders

This four-pack of white polypropylene binders fits standard letter-size documents and uses back-mounted metal rings so pages lie flat. Clear, nonglare overlays on the covers and spine let you insert custom title sheets for quick identification. Each binder has two internal pockets that add extra storage. The bundle suits offices, classrooms or home filing systems that need multiple matching units.

Upgrade from smaller ring binders

The 0.50-inch ring diameter replaces thinner binders when you need to keep up to 125 sheets in one volume without bulk. The jump is worth it when projects grow past the capacity of quarter-inch rings but do not yet require a full-inch spine. Back-mounted rings reduce page curl compared with side-mounted designs. Binders without clear overlays or internal pockets cannot match the organisation level here.

125-sheet capacity with pocket headroom

Each binder comfortably holds 125 letter-size sheets on the rings while the two internal pockets store an additional 30 sheets each for loose handouts or reference pages. The polypropylene cover resists everyday wear and the chipboard core keeps the spine rigid. Capacity runs out when a single project exceeds 125 sheets or when pocket contents push past 30 sheets per side.
