This is a new material that is being distributed by Berea Hardwoods.
It is COMPLETELY AND TOTALLY opaque. No need to paint the interior of the material, or tubes.
The material thickness at the cap is only .060". That's impressive with a light colored material. I experimented with the white shade of this material, and I kept turning it thinner and thinner until it basically fell apart. No brass would show at all even up until it shattered from being so thin.
I'm very impressed with it.
If I use brass on my pens, I try to minimize how much I use. Usually only enough to house the fittings. Or I many times just eliminate the brass.
Either way, I always found that lighter colors never lent themselves to my designs due to the transparency. If there were brass, it would show through, or if I'm making a section, I don't like the housing to show through.
So now I have a lot of avenues for some light colored designs that never really existed for me previously.
It has a low melting temperature, so you have to peck drill and watch heat, but other than that it turns beautifully and takes a fantastic shine.
I was also impressed with how it took threads. I thought that maybe it would be too brittle, but for kitless pens, I found it to hold threads beautifully.
Good stuff. I was going to link the page at Berea Hardwoods, but the website is down right now.
I think that Baumbeck and many others will be distributing this stuff, but for now, you can find it at Berea.
