Stone Geo Roll Stopper Fountain Pen - $150

Simple is beautiful! It is a clip-less fountain pen with a basic geometric roll stopper on the cap. Like its predecessor, the Stone Mask, it has a stone like surface texture. The stoppers are available in three geometric shapes: spherical, cubic, and pyramidal.

The pen barrel, cap and section are 3D Printed in Alumide (Nylon powder and Aluminum powder mix). It feels like a granite stone. It is available in polished (smooth) and unpolished (grainy) surfaces. The polished surface is smooth but not glossy, it's more like a satin. The unpolished surface is a little bit grainy, like a freshly cut granite stone. The pen has been treated with water proofing sealant, so staining on the pen is minimized. The quality of the 3D printing is excellent, with no layer lines visible. You won't notice that it was 3D printed unless someone tells you it is. *Although it feels like a stone, it's not heavy like a stone.

The pen has been treated with waterproofing sealant. However, It's not 100% stain proof.
