Prototype Popstop Mini Fountain Pen – Mustard with Brass bookweight The weights are solid barsThis is a prototype pen with a deployable rollstop. Simply press the colored circle in the cap against the sharp edge of a table and the rollstop pops out. Leave it this way or leave it flush for a streamlined look. Or, push it out entirely with a pencil for a unique look or to use as a lanyard hole. This mini version makes a great pocket pen at just over four inches long.
