The gridded series of pages allow you to use any size target and then assign a unit of measure to the gridded lines to make pin point adjustments or shot corrections. This set comes with 10 double sided pages.
In an effort to clarify and reduce phone calls and emails, our refill pages ONLY fit in our binders and only for the proper book size. Therefore, unless you have a binder from us, it is safe to say that 99.99% of the time our refill pages will not work in another binder you may have laying around.
