The Preppy features Platinum's patented "Slip and Seal" cap design that keeps the nib from drying out for a year or longer without use.
This pen's colored body, clip, and feed match the ink inside so that you can find the correct color with just a glance. The nib size is also printed on top of the cap to help you pick out the right size.
