I found some doing a quick Google search. There's
these, which are originally done by Newsea and were offered for free, but were zorched along with the rest of their old stuff when they moved to T$R and scrapped the old site. Hence, someone offered them up on SimsCave (registration needed to view and download in this section, I believe).
I've seen these in white, as well, but I'm not sure if the file includes both black and white or just the black.
