Travis,
Nice work on some of those pens.
NB: the following is my personal opinion, value it as you wish.
I think you misread the intentions of both previous posters; their comments to you should be seen as "problem avoidance".
The appearance of impropriety is almost as bad as an actual unethical action.
It's the reason our criminal justice and judicial systems work as they do.
Personally, I'd have a large disclaimer
at the top of the Pen Styles page indicating said images are from a vendor's catalog.
Your pens look good enough that you don't need a single prospect to visit your web site, see that page and leave with the wrong impression. Again, it's not always what you do so much as how it appears that matters to your potential customers.
Welcome aboard and good luck with your sales.
