Genuine Pentel LR7 refill that returns black liquid gel ink to your EnerGel pen. The 0.7 mm metal tip lays down a smooth medium line that dries fast enough for left-handed writers, and refilling keeps the pen you already own in service.

• Fits Pentel EnerGel 0.7 mm pens: BL57, BL77, BL107, BL117, BL407, BL437, BL2007, K600, K611
• 0.7 mm metal tip writes a medium-width line
• EnerGel liquid gel ink writes more smoothly than the leading gel brand (Pentel internal testing on standard writing paper)
• Fast-drying ink resists smears, smudges and globs
• Refilling instead of replacing the pen cuts plastic waste
