Rollerball pen set in a stand-up box features 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. Plus, its versatile design writes elegantly on multiple surfaces and is suitable for carbon copies.
