This device can punch up to 20 sheets of paper at one time

　　The DuraCoil is compatible with spiral coil binding elements. These supplies come in a rainbow of colors (red, pink, blue, black, green, etc.) so you can select a coil that really complements your document. These coils can bind books containing a little bit more than 400 pages.

　　One of the best things about the DuraCoil is its construction. This device has been made almost entirely out of metal, which makes it incredibly durable and suitable for many years of use.

　　The DuraCoil is priced so that just about anyone who needs this type of machine will be able to afford it. Plus, it's backed by a one-year warranty.
