The Triplus Rollerballs have a smooth writing .4mm tip and an ergonomic, triangular shape to help you maintain a relaxed grip during prolonged writing periods. Dry-safe, water-based ink can be left uncapped for days without drying up for cost-efficient use. Airplane-safe construction uses automatic pressure equalization to prevent it from leaking during flights. Pressure-stable, long-life metal tip provides a pleasantly smooth writing experience for legible results.
