Uni-ball Signo 307 Gel Pen

Uniball 207 vs 307

The Signo 307 is the follow-up model to Uni-ball’s classic Signo 207. The 307 is a newer models, not a replacement or upgrade to the 207 though — while the 307 has a newer design and updated styling it has a number of cost-cutting measures that make it in some ways a step back from the 207.
