The Uni-ball Signo 207 and 307 are similarly named pens that are often sold alongside one another. As you can gather from the name, the 307 is the newer pen, but is it a better buy than the longstanding 207? Let’s find out.
207 vs 307: What’s Different?
While these are both office-ready gel pens often sold at big box stores (Staples, Office Depot, etc.) there are some significant differences between the two.
Here are the differences with the build of the pens:
- The 207 has a metal clip while the 307’s is plastic
- The 207 has a chromed plastic front tip where the 307’s is black
- The 207 has a grey translucent barrel where the 307’s is a faux carbon fiber
When it comes to writing, the two are nearly identical except that the 307 is much more limited in its offerings. The 307 is primarily sold in 0.5 mm (micro) and 0.7 mm (medium) tip sizes. It is also available in 0.38 mm (ultra micro), but only as a Japanese import. The Signo 207 is sold in 0.38 mm, 0.5 mm, 0.7 mm, and 1.0 mm (bold).
In the USA the Uni-ball 307 is only sold in red, black, and blue ink colors (more are available in Japan). The 207 is sold in black, blue, red, purple, green, orange, pink, and light blue. But note that the black, blue, and red are sold in all sizes where the other colors are only sold in 0.7 mm (medium).
There is also the matter of styles. In the video the 307 and 207 retractable versions are features. These are the obvious comparisons and the main versions of the pen — the only version in the case of the 307. The 207 is sold sold in the 207 BLX (different colors), a needletip retractable, the Pink Ribbon RT, Impact RT, and finally a stick (non-retractable version), the 207 Impact.
