The Uni-ball Jetstream SX-217 Rollerball Pen 0.7mm combines ballpoint reliability with rollerball smoothness via low viscosity hybrid ink. This 11.8g tool outputs a 0.35mm line width using a tungsten carbide ball. Under the updated design, the grip uses elastic rubber instead of plastic for better friction. With a metal clip replacing the old plastic version, the pen holds more securely to paper stacks or pockets.
Key Features
- Fast-Drying Hybrid Ink: 9x faster drying speed than standard ballpoint pens. Smudges don't occur, aiding left-handed writers.
- Uni Super Ink: Pigment-based formula resists water, fading, and chemical fraud. Text remains legible through heavy sweat.
- Twin-Ball Mechanism: Internal system prevents backflow and ink leakage. Stops blotches from ruining paper.
- Elastic Rubber Grip: High-friction textured surface on the 11.8g barrel. Fingers don't slide during use.
- Tungsten Carbide Ball: 0.7mm tip produces a consistent 0.35mm line. Hardened material prevents tip deformation.
