Owners Manual Binder Coil... where to get?

I've seen people mention replacing the white side binder coil... where can I get the right one that works? Which one? Do they have at Office Depot?

thanks!

OfficeMax/Office Depot has the binding. It is slightly different, but it is very close. The material is slightly thicker and, unfortunately, it is bright white.

I have some, PM me your mailing info and Ill send you a couple. You too Jacques.
