I know I’m late to the game on the Uniball Signo 307 but I think it’s a great pen worth reviewing. While playing with the 307 I was reminded of the days before my real focus was fountain pens. I would frequently wander the aisles of the big box stores looking to see if I spotted anything new in the writing instruments section. I couldn’t really keep track of all the models and manufacturers of what I had already bought so occasionally I would end up with something I had already tried. Most of the time I just got sucked in to cheesy marketing when NEW AND IMPROVED was printed on the packaging. That might as well have been a catapult from the shelf to my buggy.
In the past couple of years I have not been a big disposable roller ball or gel pen user but you couldn’t tell that from the inventory of same sitting around my house in every drawer and open counter space. All of them get picked up and used for convenience. Most write well and get the job done and probably end up getting borrowed, lost or broken before the ink runs out.
When I read all the recent reviews on the new 307 I looked around and found a Signo 207. Frankly it didn’t make the top of my list but not because it was a bad pen but just nothing stood out for me. With my NEW AND IMPROVED interest piqued I actively searched out and purchased a Signo 307 for a compare and this review.
Aesthetically I like the 307 slightly better the obviously comparable 207 but that is totally subjective. I think the 307 has a slightly more modern look to it, which is no surprise. They are very similar. The 307 has a subtle grid gradient on the barrel that gives a bit of a carbon fiber look that’s popular today. The 207’s barrel in smoky transparent where the 307 is black. Also the tip surrounding the writing point was changed from chrome on the 207 to black on 307.
The clip on the 207 was chrome metal and in what appears to be the only downgrade the 307 went to plastic. Maybe a cost saving measure? They both seem to hold ok but I have to believe the metal would win out in a durability match.
No changes here that I can tell. The rubberized grip with the little nubbies is comfortable to hold. Average length, diameter and weight in line with most disposables in the class. The retract works smooth with a definitive click loud enough to drive your cubicle neighbors crazy.
The biggest advertised difference is the use of Uni-ball’s Super Ink technology in the 307. The promotion of the ink seems more geared towards its proclaimed permanency than the smoothness and writing experience. Uni-ball appears proud of the Uni Super Ink technology, which assuming their claims are true, it’s pretty impressive. From the Uni-ball website:
- “…. The color particles of uni Super Ink stay suspended, the ink is not soluble in water or solvents. The uni Super Ink won’t wash off when immersed in water, acetone, glycerin, bleach or other chemicals used by criminals. Once on the page, uni Super Ink can never be removed….”
The 207 and the 307 both write well. Smooth with no skipping or ink blobbing but nothing really special to report. I will admit I was intrigued by the claim that nothing will get the ink off the paper. I fancy myself a bit with having a wide range of cleaning chemicals stocked in my garage for a variety of household projects that come up. No muratic acid but the toughest I get to is automotive brake cleaner which if you’ve ever let that stuff sit on your hands. Well it’s pretty strong and can be a good substitute for pepper spray, but that’s for another post.
I started with a sheet of good paper HP Premium Choice Laser 32lb. I figured the paper should at least be able to hold up to the chemicals. The magic formulas I tried with the 207 and the 307:
- Goo Gone
- Greased Lightning
- Simple Green
- Purple Power
- Mechanics Hand Cleaner
- Household bleach
- Rubbing Alcohol
- Denatured Alcohol
- Gumont Carb & Choke Cleaner
- Gasoline Unleaded 87 octane
- CRC Brake Parts Cleaner
Maybe the 207 was converted to the Super Ink formula already?
Permanent or Removable?…Uni-ball’s Super Ink claims are not far off. I would say it’s pretty permanent. Now whether that’s any value to you or not I can’t tell but it was fun stinking up the garage all in the name of research for you dear readers
I like the 307. I didn’t use the 207 extensively to fairly compare the two but others have said the 307 is a slightly better writer. It’s smooth on a variety of media, I did not experience any skipping or ink blobbing and the ergonomics are as good as in disposable I have used.
Are you a big fan of the 207 and have you tried the 307 yet?
Remember: Write something nice……
