Capped gel pen PENTEL EnerGel BL57-DO — green ink, green and silver body

PENTEL EnerGel BL57-DO is a capped gel pen featuring green gel ink and a green-and-silver body. The pen is designed for smooth, consistent writing with quick-drying EnerGel ink that reduces smudging and bleed-through on most paper types. A removable cap protects the tip when stored and helps prevent the ink from drying out during periods of non-use. The balanced barrel and moderate diameter make the pen suitable for extended writing sessions and everyday tasks.

Advantages

The EnerGel formula delivers low-viscosity gel ink that combines the smoothness of gel with rapid drying times, improving legibility and minimizing smears. The capped design ensures reliable protection for the nib and helps maintain ink performance over time. The green ink provides clear color contrast for annotations and highlights without requiring highlighter pens. The exterior finish in green and silver offers a professional appearance appropriate for office and personal use.

Key specifications

• Writeability: smooth, low-viscosity flow

How to use

Remove the cap before writing and replace it after use to protect the tip and preserve ink quality. Apply light to moderate pressure while writing; the low-viscosity gel ink flows evenly without the need for force. Store the pen horizontally or tip-up when not in use to help maintain consistent ink delivery. If the tip becomes clogged, recap the pen and shake gently or scribble on scrap paper until the ink flow stabilizes.

Usage recommendations

For best results, use on standard paper grades commonly used in offices and notebooks. Avoid prolonged exposure to direct sunlight and extreme temperatures to preserve ink performance. When transporting, keep the cap securely in place to prevent accidental marks and drying of the tip.
