Little bag of cotton material in package?

[Grinch]

Hi, I know this is a stupid question, but I've occasionally gotten a little bag of cotton filler material with my order. Is this meant to be used to pack your own cartridges? Because that's what I've been using it for, I just wasn't sure.

Thanks!
