7 Mil 8-1/2 x 11 Inches PVC Binding Covers – Pack of 100, Clear Compatible with GBC, Fellowes and Trubind Binding Machines and More

I am a student and have lot of materials from the course . Recently I got Tianse binder and started to organize my notes by making custom made note packets using my wonderful binding machine. I felt the need to put a plastic sheet on top and behind the note, to reduce damage while using the notes. I ordered this and found out to be the exact key for my lock !!!! It works on my tianse binder and exactly what I had in mind ! really happy with this purchase.
