Pentel EnerGel RTX Retractable Gel Pen 0.7mm Metal Tip Black Ink Pack of 2

Pentel EnerGel RTX 0.7mm Retractable Pen

The Pentel EnerGel RTX is a retractable gel pen with a 0.7mm metal tip that delivers a medium black line. Its liquid-gel ink formulation merges the smooth flow of liquid ink with the quick-drying properties of gel. A latex-free ribbed grip provides comfort and control during extended writing sessions. The pack contains two pens suited for everyday office or school use.

Fast-Drying Ink for Sustained Writing

The liquid gel ink dries rapidly so that continuous writing does not produce smears or smudges, a benefit noted by left-handed users. During long periods of note-taking or document signing the ink maintains consistent flow without globbing or skipping. The retractable mechanism protects the tip when the pen is paused, keeping the ink ready for the next line. Performance remains steady across the full length of a writing task.

Practical Limits of Water-Based Gel Ink

The water-based ink is not water resistant, so exposure to moisture can cause lines to blur or wash away. Documents that must survive spills or outdoor conditions require a different ink chemistry. The 0.7mm medium point lays down a line width fixed by the tip size and cannot be adjusted finer or broader. The metal tip withstands normal writing pressure but is not designed for heavy marking on abrasive surfaces.
