Professional Writing Tool

The Pentel EnerGel RTX BL77-A is a retractable liquid gel pen with a 0.7mm medium line and metal tip. It uses high-performance ink technology that combines liquid and gel properties for a super-smooth writing experience. The sleek barrel features metal accents and a latex-free grip for comfort and control during extended use. This box contains twelve black ink pens suitable for office and professional environments.

Sustained Writing Performance

Liquid gel ink dries quickly to prevent smears, smudges, and globs even during continuous writing sessions. Left-handed writers benefit from the fast drying time that eliminates ink transfer across the page. The refillable design supports long-term use without replacing the entire barrel. Internally tested ink flows more smoothly than the leading gel pen on standard writing paper for consistent output.

0.7mm Medium Line Width

The 0.7mm tip produces a medium line width that determines suitability for general writing, note-taking, and document signing. Buyers who need an ultra-fine line for detailed technical drawings or a broader stroke for bold signatures should consider a different tip size. The metal tip construction supports durability for daily writing tasks. Each pen measures 2.8956 L x 7.1882 W x 15.0114 H centimeters and weighs 0.159 kilograms.

Questions about this item

Does the 0.7 mm metal tip generate any heat or noise during long writing sessions?

The liquid gel ink and metal tip produce no heat or noise, so the pen stays comfortable and silent even after hours of continuous use.

What refill must I already own to keep using the BL77-A once the original ink runs out?

The pen is refillable with Pentel EnerGel 0.7 mm needle-point refills, which match the original tip size and ink formula.

Will the RTX retractable mechanism still operate smoothly if I switch between this pen and an older capped rollerball?

Yes, the RTX click action works independently of other pens, so alternating with a capped model does not affect its reliability or feel.
