Uni-ball Signo Erasable Gel Ink Pen - 0.5 mm - Sky Blue

I purchased and tried each type of erasable pen offered at JetPens (three different Frixions, the Uni-ball Fanthom, and this Uni-ball Signo) and the Uni-ball Signo was far and away the worst of the bunch.

It looks nice and it's convenient to have the eraser on the cap so you don't have to remove the cap every time you want to erase, and it writes adequately (-- not great, but adequate), but the erasability was very poor: the eraser only served to fade the ink rather than erase it, and it was the only erasable pen wherein the eraser wore down notably as you used it.

The other erasable pens (Frixions, Fanthom) actually are erasable, and I tried mixing erasers and pens (using the Signo to erase a Fanthom, and using the Frixion to erase the Signo, etc.), and found both the Signo's eraser and the pen itself to be very poor at erasing/being erased.

Stick to the Frixions or the Fanthoms.

I don't really expect a lot out of erasable pens and these are no exception. The ink is watery and takes quite a while to dry. It seems more like liquid ink then gel ink. Only when the ink is completely dry will it erase and even then, some of the color is still left behind. Another thing is that after a while, the writing on the page starts to smudge and fade away. This makes the pen even less appealing for me. The only things I like about these pens are that they work on every notebook I have (they don't skip) and the color is nice. Sometimes it takes a bit for the pen to start up, but after that there're no problems. Overall, these pens are okay, but you can do a lot better. They're currently my last option when it comes to writing instruments.

I didn't actually expect this pen to work. I remember the "eraseable" pens from the late 80s, and how the eraser would wear a hole in the paper before actually erasing the ink. Hope springs eternal, though, and this time, it was worth the wait. The pen writes smoothly, the ink is a medium blue, and, though it does not completely disappear when erased, it certainly erases well enough to fix an "oops" here or there. I was pleasantly surprised, and will probably order some more when they're back in stock.

The ink doesnt erase all the way but the black is very pigmented; l would recommend the pilot frixon if you want a pen that erases better!

I wish I read alli's review and stopped.
These pens are very poor quality. They do not erase. They lift the ink up slightly but that is all. The rubber eraser actually makes a mess and wears very quickly.
I wish I never spent my money on them!
