This Durable Binder features sturdy construction that's ideal for frequent referencing. It has wider front and back panels to fully cover standard dividers and sheet protectors. The slant rings offer higher page capacity compared to the same-size round rings, and pages lie flat with the back-mounted rings. Its 375-sheet capacity and two interior pockets provide plenty of room to store three-hole punched and unpunched paperwork.This Durable Binder features sturdy construction that's ideal for frequent referencing.
