Do you like the touch and look of wire binding but you don't have a wire binding machine? Have no fear! Spiral-O wire binding spines are here to solve your problem! These spines work with a 19 look plastic comb binding machine and a wire closer. Their sheet capacity ranges from 40 to 200 sheets of 20lb paper. We offer 10 various sizes to choose from, too. If you're looking for the clean, minimal look, then check out these white wire spines-with a white cover, they'll look modern and sleek. Or with a colorful cover, they will add a bright contrast.
