Fellowes Thermal Presentation Covers - 3/8 Inch Clear Front with Linen Textured Black Back - 10-Pack (5256101) - Perfect for Business Reports, School Projects & Professional Document Protection

I bought these covers to be used with my "MARIGOLD Document Thermal Binding Machine - Perfect Glue Thermal Binder (TB200)" and it works like a charm: all you do is slide the set of documents into the presentation cover, plop it into the binder's slot, wait a couple of minutes and you are done. I have bound a bunch of employee handbooks and they all came out perfect. I didn't have any "loose sheet" or sheets that didn't bind, like some other customers described. I think what was key to my success was choosing the right sized covers. My employee handbooks are 59 pages, so I chose the 30-60 page cover. I also bound SOP manuals that are 24 pages, so I chose the 15-30 page covers. I think as long as the user chooses the correctly-sized cover, they will have 100% success with these covers -- at least when they use it with the Marigold binder.
