While the core Preppy mechanism remains the same — including the Slip \u0026amp; Seal cap and smooth nib — this edition is designed to be purchased and used as part of the PERPANEP writing ecosystem, where pen and paper are chosen together for a matched experience.\u003c\/p\u003e\u003ch3\u003eWhat is the Slip \u0026amp; Seal cap mechanism?\u003c\/h3\u003e\u003cp\u003ePlatinum’s \u003cstrong\u003eSlip \u0026amp; Seal\u003c\/strong\u003e is a patented inner cap design that creates an airtight seal around the nib when the pen is capped. This prevents ink from evaporating or drying out — Platinum claims the pen can sit unused for \u003cstrong\u003eup to one year\u003c\/strong\u003e without the nib drying out.
