EnerGel RTX Liquid Gel Pen 0.7mm Assorted 12-Pack - Smooth, Fast-Dry

In this review the Pentel EnerGel RTX liquid gel pen is evaluated for everyday writing, note-taking, and professional use where smooth, smear-free ink matters. The single biggest reason to buy is the pen's fast-drying ENER-GEL ink that blends the flow of liquid ink with the control of gel ink, making it especially useful for left-handed writers and anyone who needs a clean, consistent line. The included 0.7mm metal tip delivers reliable medium lines from a sleek barrel that feels more like a premium roller than a bargain pen.

Key Features

• Fast-drying ENER-GEL ink: Writes smoothly with quick dry time to minimize smears and smudges for left-handed and right-handed users alike.
• Liquid gel performance: Combines the flow of liquid ink and the density of gel ink for a consistently even ink delivery across the page.
• 0.7mm metal tip: Produces dependable medium lines suitable for notes, forms, and everyday handwriting without skipping.
• Sleek barrel with metal accents: Feels professional and balanced for extended writing sessions while looking appropriate in office settings.
• Latex-free grip: Provides comfort and control during long use and avoids common grip allergen concerns.
• Refillable design: Accepts ENER-GEL refills so the barrel can be reused instead of discarded, extending product life.

Who It's For

The EnerGel RTX is best for students, office workers, and left-handed writers who need a smooth, fast-drying pen for daily tasks. Its medium 0.7mm tip and steady ink flow make it ideal for note-taking, form filling, journaling, and meeting notes where legibility and speed are important.

Those who need ultra-fine technical lines, archival pigment ink, or extremely long-lasting low-maintenance pens for heavy daily use may want to consider alternative writing systems. Also, if you prefer a bolder line the 1.0mm tip version is the better choice.
