The Pentel EnerGel Deluxe RTX (BLN77) is a retractable liquid gel pen featuring a fine needle tip at 0.7mm medium point for crisp, precise lines. The pens deliver blue ink with an ultra-smooth writing experience powered by Pentel's exclusive EnerGel ink technology, which combines the best characteristics of liquid and gel inks.

The quick-drying formula is designed to eliminate smears, smudges, and globs — making these pens an excellent choice for left-handed writers. Each pen features a comfortable latex-free grip for extended writing sessions, a sleek retractable mechanism, and a refillable design compatible with any EnerGel refill. The barrels are made from 54% recycled plastic as part of Pentel's Recycology eco-friendly line. This Costco pack includes 6 pens in blue ink.
