Binder features a unique XtraLife material that will not stick to cover title insert or materials stored inside, including photos, laser prints and photocopies. Material is much stronger than standard vinyl so no seam splitting and hinge tearing. Binder is cold-crack tested to negative 50 degrees Fahrenheit. Locking slant-D shaped rings hold 25 percent more material than standard round rings while GelTab triggers make it comfortable to operate. Horizontal pockets are on the inside front and back covers.
