Looking for a Latex or Gel Ink Pen

I saw someone decorate their latex weapon with what looked like a latex ink pen, with bright gold ink. I'm hoping to do something similar, but can't find a product I'm comfortable buying, as I'm not certain if its the same. Does anyone have any suggestions?

Thanks in advance!

A number of art supply stores sell these new pens that are used to paint models.  Japan made a bunch of famous Gundam Ink Pens that can be used on their plastic models.  Other manufacturers have started the same...

You can find some here.

Thanks much! I can't tell but are these fine tip pens? I"m looking to highlight deep grooves in a latex weapon and thick tip won't do. Curious if you (or anyone else) have used a particular brand to recommend. Looking for Gold or a dark Brown color.

Thanks!!

The pens are like paintbrushes/other pens... some are fine tip, others are broad.  As for recommendations... not sure as you're working on latex.  My experience with the pens are on plastic, metal (lead/pewter), and wood.  Never used them on latex.

I have one of those gold paint pen things somewhere, you can definitely borrow it if i can find it haha

That would be awesome, but if you can find it, I'd love a post that tells the brand and any other identifying info so I can just buy my own. I otherwise would be happy to borrow it from you Thanks - MC
