No tubes on this one. The cap is a little thinner than the barrel, and is a little translucent if you hold it up to a strong light.
IMHO, it's really purple when turned down, not quite dark red enough to be a true burgundy. Of course, that could be the particular blank or my ancient particular eyes!
Gorgeous pen with outstanding design and color match! I really would like to learn how to do a kitless like that. Your pen is inspiring..and thanks so much for showing. Doc
Nice look and I am surprised at the opacity--you tied in your black sections really well---Just a great look--again, thanks for showing!! Maybe we can get you to add it to our gallery?!?!?!?!
