Yes, that is it (ones sans any added cleaning agents).
My original pack of them has a finer grain than later one's, but no-one has complained about the later variation(s).
I stick a slice of it down to a small piece of thick paper, but have a tonearm up/down control like the one in the following video.
I would not trust my doing it solely by hand @ this point in time, but I'm 68.
Lot's of info here in the forums on the best way to use it.
