Ed it reminds me of Velvet smooth as great pen for the wedding business or pleasure.
Surprise material Corian certainly better in larger sizes my horror used to be cutting 7mm holes in 1/2 inch material in all colours the surprise is the variation in where the colour ends up at the end some Corian is uneven when they make it as well. It feels great out here in the warmth but in the winter SWMBO says in general it feels uninviting sometimes in the hand while timber has warmth.
I dont use it much any more preferring timber but do like the variation in your pen for this purpose.
Great pen mate.
Kind regards Peter.
