The first pen JetPens ever carried, the Hi-Tec-C is a humble-looking pen with a well-deserved and enthusiastic following. Its precise needle-point tip is specially designed to provide minimal drag and effortless ink flow. The pen's vivid gel ink is made of a special biopolymer resin whose high viscosity prevents feathering and bleed-through. The ink has enough water resistance to prevent your notes from getting ruined by spills or rain, but it is also soluble enough that artists can create subtle shading and wash effects with a water brush.
