uni-ball Signo 307 Gel Pen, 0.7 mm

Uni Signo 307 is a super-smooth retractable pen with dark, fade-resistant ink that makes a bold impression. These pens use a special, low-viscosity gel ink that flows through the tip with no skipping, blotches, or stickiness. You still get the luxurious, smooth feel of a gel pen, but Uni's proprietary Nano Fiber Ink dries more quickly and offers a dependable, clean line.

The plastic body is well balanced and features a rubber grip for control and comfort. A strong spring makes the retraction mechanism quite clicky and satisfying. There's also a pocket clip made from strong, slightly flexible plastic.

0.7 mm line width. Sold individually. Made in Japan.

Signo 307 is refillable. Spare cartridges are available here.
