Mother of Pearl


This color is somewhat transparent. For penmakers, the tubes of your pen will show through.

Paint the inside of the hole different colors for a different effect.  The pen shown below has the tubes painted white.

Officially considered a non-pliable blank but turns more like an acrylic blank or polymer resin.

Similar in properties to the tortoise shell. This color is slightly brittle.
