Arrived in white instead of black - but that is a mistake on Shapeways part. The design itself is solid. It fits well and looks great both on its own merit and as a homage to the Elder Scrolls.
I tried "Strong and Flexible." The texture and specularity is very different from that of the ABS plastic traditionally associated with LEGO and Brick Arms. That contrast is something to be considered.
To the touch, it feels like a cross between sandstone and paper mache which is more than a little odd. Visually, up close, the difference in material is readily apparent. It has a weathered / rough aspect which some might find to be jarring or desirable. At a distance this is not really something you'll notice.
I have not tried frosted or polished metallic plastic. These might look and feel more familiar.
In white, this design looks fantastic on Fantasy Era skeletons.
