You can use the patented Fastbind Manager DuoStrips with the new generation of Fastbind binders (Secura, Elite and Ultra). Fastbind Duostrips allow you to bind with two separate covers (for front and back). You can even create a nice looking binding without any cover.

DuoStrips are available in four standard colors: black, dark blue, dark red and white. The three standard sizes allow you to bind up to 13, 26 or 39 mm thick, in A4 format.

Manager DuoStrips are sold in boxes of 100 and 500 pieces.
