I saw this prisma pen being advertised/sold on some ebay auctions with reborning supplies. They say it works well for veining. It’s a double ended (fine/broad) pen always in the color Light Cerulean Blue. Has anyone ever used this type of marker for their veining?

Good question!
Try it on a test piece! 
I don’t have one, I just saw them being sold online. I’m open to anything that makes veining easier and more consistent, but wanted to find out from anyone here if they’ve used it before.
That’s something I wouldn’t want to use. I like mixing my own, and having more control of the right shade of blue.
It reminds me of when people used sharpies for veins. Didn’t like that one bit though.
I don’t know about this pen since it is made by prisma but I have heard people that used pens/markers said they were awful. They make very dark veins and then they are very hard to remove or lighten, Be careful. I am only repeating what I have read. Maybe you could try the spyglass and see what information you can find. I know it’s out there.
I’d stay away from the pen. It would be too easy to mere the veins too dark. And there’s no going back.
My art teacher has these exact pens (about every color they ever made probably) and the cerulean blue is very light/translucent and I could actually see these working. These markers are very much like prisms pencils! The fine point end that is.
Tomorrow while I’m at school I can get pics of different blues on paper if you’d like! Cloud blue is probably another good blue you could use.
it would be very hard to blend in…to fade in …IMO …it would be like a perfect line…when we use the pain some parts will be lighter, softer, more blended other places darker so would look more natural then the line with a pen… I seen this at Michale’s and I was thinking on it.
