**** Update: When I got home and settled down I did some research on the Internet as to where you can find these. This is what I found, KaiserCraft I have the 8.25 X 6 binder with the 6x4 storage packs. I also bought the magnetic pieces to hold my spellbinders.
This is what it looks like inside I put two magnetic sheets back to back in each pocket, so depending on the size of your spellbinders you might be able to fit more than one set on a sheet.
