Inventery Pocket Fountain Pen Kit

An independent design house based in Los Angeles, Inventery takes its writing tools seriously. How seriously? Each of its pocket fountain pens is not so much a pen as a writing kit—with interchangeable caps and tips that let you use yours exactly how you want. Insert the Schmidt FH 241 fine-point nib or opt for the 0.5-millimeter interchangeable PRS ballpoint head. Then, screw on the cap with a pocket clip, the clipless cap, or the cap with the handy keychain attachment. There’s even a cap with a universal stylus for use on your touchscreen phone or tablet. The compact body measures 4 inches, and you can add length by posting the cap to the back. If you prefer a full-length pen, pick up the optional extender, which also comes with a Schmidt standard international converter.

Inventery specializes in stationery products and fine writing tools. Its pens are precision machined from raw metal stock and its machining process is precise to a fraction of a millimeter. The company uses only high-quality materials and sources the finest parts available—like German-engineered mechanisms, fine writing nibs, and refills. Inventery has an obsession with simplicity, pure forms, and seamless objects. Its products are unadulterated by style and over-design, and its tools are made to last a lifetime.
