The DURACLIP is the original punch-free report cover since 1959, developed by DURABLE, and still made in its German facilities. A strong "memory" clip expands to hold contents securely and returns to its original shape after use. The clip has a five-year guarantee. Each report cover is made of sturdy vinyl with clear front to show-off contents while protecting them from the elements and accidents. With a 60-sheet capacity for 11 x 8.5 inch (letter size) sheets, each DURACLIP Report cover has a colored back and spine with a clear front cover. Durable is an office supplies manufacturer that has risen to the highest ranks among German brands and is celebrating more than 90 years in operation.
