Uni-ball Signo 307 Retractable Gel Pen, 0.7 mm, Quick Dry, Smudge Free, Comfortable Grip, Ideal for School & Office Use - Black

Key specs: 0.7 mm tip, quick-dry Uni-ball Super Ink, retractable one-hand click mechanism, textured/comfortable grip, and regulated ink feed for smooth, even lines from start to finish.

A 0.7 mm tip produces moderately bold, highly readable lines that are great for forms and notes. It offers clear, tidy writing without excessive feathering, making it a good balance between visibility and control.

Yes. The Quick-Dry Super Ink is designed to minimize smudging on most paper types, helping your notes stay clean and legible even when you’re writing quickly.

The retractable mechanism protects the tip when not in use and prevents cap loss. One-handed clicking lets you advance or retract the nib quickly, keeping your writing flow uninterrupted during meetings, classes, or forms.

The pen features a textured barrel that provides a comfortable, steady grip, reducing hand fatigue during extended writing sessions at school or in the office.

This model uses standard Uni-ball Signo 0.7 mm refills (UMN series). To replace the ink, separate the barrel, remove the spent refill, insert a new UMN refill, and reassemble. This keeps you writing with consistent ink flow and performance.

The Signo 307 performs well on standard printer paper, notebook paper, and forms. It may be less ideal on highly glossy or coated surfaces where ink adhesion can vary.
