Tactile Turn Side Click Pen - CopperElegant and simple. The all metal Side Click is incredibly satisfying in both feel and sound. We designed a completely new, two piece mechanism that's durable enough to withstand a lifetime of use. Fair warning this is an extremely addicting pen. The Standard [5. 8"] comes with a Pilot G2 0. 7 mm refill, the Short [5. 3"] comes with a Schmidt EasyFlow 9000 medium refill, and the Mini [4. 6"] comes with a Pilot G2 Mini 0. 7mm refill.
