We love to use artisan resin makers when selecting materials. This one comes from a fellow Texan at mutt blanks. They use ribons of off-cut blanks and embed it in a translucent base color, in this case purple.
The pen is translucent, but not polished on the inside. It's a bit longer than our normal pens and a bit more in diameter (15.5 mm).
Still comfortable and well balanced.
Really wonderful pen. Feels great to write with
