Carstens 1.5-Inch Heavy Duty 3-Ring Binder - Side Opening, Teal, Durable Plastic, Precision No-Gap Rings, Waterproof Covers, No Pockets, Holds 250 US Letter Sheets, BPA-Free, Made in USA (2043-3R)

Carstens Heavy Duty Ring Binders are made from premium Copolymer Polypropylene plastic to resist tearing and bending in even the most demanding work environments.

The No-Gap steel rings are tested for over 50,000 uses right in our manufacturing facility to ensure they hold tight and stay aligned.

The 3-inch ring models hold up to 400 sheets, 2-inch models hold 300, 1.5-inch models hold 250 and the 1-inch models hold 125.

Our non-porous binder surface is impenetrable to air and liquids, so bacteria cannot grow beyond the surface – versus standard vinyl binders that can absorb liquids and harbor bacteria.
