Having a pen or stylus handy is a must in this age of electronics; the new Quiver Pen Holder is an elegant solution.
The leather Quiver looks like a long, thick leather bookmark, with a built-in pouch for holding a pen, stylus, pencil or other writing implement.
It attaches to the hard cover of your notebook or electronic device (up to the size of a tablet); a steel spring helps keep the Quiver flat. Quivers come in a range of sizes to accommodate the multiplicity of electronics.
Colors are natural shades of tan or black, and the stitching is with marine-quality thread, so water won't cause deterioration (at least to the Quiver).
Info: Quiver Pen Holder starts at $24.
