Four black polypropylene binders with 1.00" back-mounted metal rings hold 240 sheets each and include inside pockets for 30 extra pages
This bundle contains four black binders with a 1.00-inch ring capacity. Each binder holds up to 240 sheets on back-mounted metal rings. Two triggers on the mechanism give quick access to documents. Clear pockets on the inside front and back covers add extra storage space.
The 5.5 by 8.5 inch size matches half-letter paper and fits compact shelves. Buyers who need letter-size or A4 documents will find these too small. Anyone wanting D-ring or slant-ring mechanisms should choose a different style. The polypropylene covers are not designed for heavy daily abuse.
The rings accommodate 240 sheets per binder, which sets the practical limit for each unit. Each inside pocket holds an additional 30 sheets. Three metal rings keep pages aligned and lying flat. Exposed rivets reinforce the chipboard core for durability.

Yes, the 5.5 x 8.5 in. dimensions match half-letter size, so it sits flush on any shelf spaced for that format.
Press both metal triggers on the back-mounted mechanism at the same time; forcing one side alone can misalign the rings.
Each pocket holds up to 30 sheets; replace the binder when the pocket seams tear or the polypropylene cover cracks from repeated flexing.
