I use Veritas, but it is an identical(?) product composed also primarily of chromium oxide in green stick form. It looks exactly the same. I use it on unfinished leather which is very soft, like sued. It works well for me, but it might work equally well on something smoother. It benefits from a dusting before each stropping and a firm hand at the stropping. It can get gummy if it gets hot so try to keep it cool.
