Cardinal XtraLife ClearVue Heavy Duty 3" 3-Ring View Binders, D-Ring, White (26330)

Huge Storage Capacity
Cardinal D-ring binders store up to 725 pages at once thanks to a proprietary Slant-D design. Compared to other 3-inch three-ring binders, you get more pages into one place, which means spending less money on larger binders. This higher storage capacity also lets you add more pages at a later time, which is ideal if you're producing related reports throughout the year.

Sturdy Construction
The unique polyolefin cover is more environmentally friendly than vinyl, while the overall binders can withstand temperatures down to -50 degrees Fahrenheit before cold cracking. XtraLife material doesn't stick to pages, plastic or dividers to prevent tearing, smudging and ripping, and these binders come with a one-year warranty on workmanship with regards to cracking or splitting along the seams or hinges.

Industry Standard
Three locking rings keep pages inside, while also allowing you to add dividers, folder pages and additional materials as your documentation needs grow over time.
