Nuova SP12 Shredder Sharpening & Lubricant Sheets

What is this?

Lubricant sheets for my paper shredder.

Why did I buy it?

I broke my first shredder by not lubing it at all. One day I went to shred and... nothing. Believe it or not, your shredder needs lube or it will just seize up and die like mine. So now I just shred one of these lubricant sheets every month or so and it hums. 

I tried to figure out what the oil inside these sheets was so I could just buy that and cut out the middle man, but after lots of searching I was no closer to my answer. Plus, I the idea of pouring lubricant into spinning blades isn't as appealing as knowing it will be (hopefully) distributed evenly.
