Uni-BallUMR-87 Gel Pen Refill - 0.7 mm - Black Value Set of 10

Fits Uniball 207 Plus body. No skipping ! Dust particles do block the flow, but only a small amount will remain in the cartridge. My kitchen table is my desk - lots of crumbs etc.

I am a pen and pencil geek: I insist on my writing implements being exactly the way I want them. I have about half a dozen TUL rollerball pens that are simple, plain black, understated, professional, and INEXPENSIVE. But the refill costs are sky high! Between $7.95 and $9.95 for just TWO pen refills!These Uni-ball UMR-87 gel refills are just the ticket. For the price of two TUL refills, I get 10 from Uni-ball. They fit the TUL pen housing ALMOST PERFECTLY. And they write just as smoothly and smudge-free as the original TUL refills did. (I'm a left-hander, so a fast-drying ink is very important!) I'm not a stickler for brand names, but Uni-ball's products are very high quality, and -- let's face it -- most of the cheaper no-name or generic pens, inks, and refills are just junk.

If you like the Uniball Signo, this is the exact refill.

My ink roller ball refills were of good quality. I'm happy!

Good value for a quality refill in a good quantity.

The Refills Fit perfect And work Great

I wasn’t sure what I’d be getting, I assumed UMR-87 per the product description, which are refills for the Uniball Signo 207. I have 307 bodies, but ordered anyway, believing they would fit, just be somewhat inferior ink (incapable of writing on extra smooth/glossy paper).But to my delight, I received UMR-87E, the refills designed for the 307. I never owned the 207, but from what I’ve been able to deduce online: while the UMR-87 ink dries slightly faster, the feel is less flowy, less wet?Anyway, ecstatic to have received 307 refills, it’s a luxurious writing experience. Pen nerds rejoice!

These pens are great. I hate throwing out a good pen. So I found these. They last long too.
