The Most Reliable Pen

Utilizing an innovative hybrid-ink system unique to the uni-ball JETSTREAM collection, the JETSTREAM 101 writes—and dries—as fast as you think. It features a soft-textured pen body that runs the length of the pen for all-day comfort and support. Bold, smooth, left-hand friendly, and filled with industry-leading Super Ink™, the JETSTREAM 101 is one of the most trusted go-to ballpoint pens.

Twin-Ball Mechanism

Utilizing uni-ball’s unique twin-ball mechanism, the JETSTREAM 101 ensures constant ink flow without skipping, blurring, or excessive flowing. As ink passes through the tip of the pen, the viscosity is reduced by the twin-ball mechanism to enable smooth writing. When the ink touches paper, it returns to its original viscosity to prevent feathering and bleeding. Down to the last drop, the innovative twin-ball mechanism guarantees high-performance writing without messy leaks.
