Pentel EnerGel PRO Permanent Ink Gel Pen, Retractable, Medium 0.7 mm, Black Ink, Black Barrel

A 0.7mm retractable gel pen with pigmented ink that's fade-proof, water-proof, and resistant to the kind of tampering fraud-proof ink is built to catch, so it's the pen for anything that needs to stay legible in twenty years. Stainless steel accents, a latex-free grip, quick-drying so it won't smear under your hand.

This is the pen for signatures, checks, anything you'd regret if the ink faded or the writing could be altered later. Everyday enough to also just be your pen, if that's what you want it for.
