Product Description
These high quality Bronze 3/8" 2:1 Pitch Twin Loop Wires are some of the best wire binding spines on the market today. Also called Wire-O, WireBind, and Double Loop Wire, these bronze 3/8" 2:1 pitch elements let pages lie flat with 360 Degrees rotation for convenient note-taking and photocopying as well as provide a permanent bind to your documents--meaning your pages stay secure and protected. Not only that, but these bronze 3/8" 2:1 pitch wire spines look a tad more refined than a plastic comb or spiral coil. Measuring 3/8" in diameter, these bronze twin loop wires can hold approximately 50-60 sheets. These bronze 3/8" 2:1 pitch twin loop wires come open in a "C" shape, allowing you to insert the spines into your punched pages and then simply use your wire binding machine or wire closer to finish your books. Product number W380BZ21.
