The James Brand Stilwell silver + silver pen

The James Brand Stilwell is a compact, modern pen with a sleek design. What's special about the Stilwell is its cap. This cap is held in place by three rubber rings that you slide the cap over. When open, you can slide the cap onto the back of the pen, making the pen a lot longer. The result? When closed, the pen is 9.1 cm long, and when open it is 13.7 cm.
