4C StylusPen Ballpoint Pen Refill, Black Ink, 1.0mm, 2-Pack

Excellent and Valuable Pen. Fits very well in small pockets, and it does not take very much space in small containers for storage. Writes very smooth, easy to use, it is not heavy and easy to grab.

These refills for perfect for my Lego pens. I was able to get 3 classic Lego pens working again. So if you have those older style Lego pens that you put together these are the refills for you.

These seem to be a bit tricky to get installed. Refill pokes out a bit more than the original.

I have a tiny white Zebra telescoping pen (SL-F1) that I purchased several years ago but is now apparently discontinued. I was happy to find these refills for it in the 4-C size. Because they are described as fitting a twist pen, I was afraid they would not fit my little telescoping pen but they do. There are two refills in the package. The pen and the refills are tiny, so of course a refill isn't going to last as long as a full size one would. It's writing fine so far so I'm rating these 5 stars. More product info would be helpful but I'm just glad these work in my pen.

Fit like original. It does take a little bit of finagling to get the top end to seat in the pen top, but otherwise fit is good and refill writes well. Side note: really find the collapsible pen useful.

I wasn't sure if this refill would fit the zebra telescopic minipen 10110, even after asking the question and the only answer was an uncertain one. I decided to go ahead and get them, if they didn't fit, I could get a refund. They do fit, so this telescopic minipen that I just found going through some old stuff, didn't even know I had this pen. It's now a usable mini pen! (gave 3 stars for longevity since I haven't used it long enough to know.)

Needed to replace my old . .very old Zebra telescopic pen. Great for a purse or a checkbook (yes, I still have one). Zebra is a brand known for its dependability. My old Zebras were probably from 2005 or earlier & I ran out of refills & the new pens have a different size. They have a medium point and write smoothly.

Best pen for the $ by far. Comfortable and reliable. I use it daily

Good

These were the correct refills for my Zebra Telescopic pen. I would have preferred Blue ink and maybe a fine point. I was okay with what was available, as these telescopic refills aren't easy to find.

Great size and stylus is useful for touchscreens.

Love using the small telescopic pens with D1 refill. Yes, small is beautiful! I don't write much, half an A4 equivalent page per day. Even with less ink in these small refills, it would last long enough (> 3-4 months) so i wouldn't notice the pinch on my pocket. This time both Zebra refills lasted only 1 month. Don't know why - maybe the stock is old and ink dried up (number on packet - RBC85612/0716 - i hope doesn't mean July 2016, 3+ yrs old); still i think paying more than a couple of dollars for these refills is not worth it. Trying other options, but with import duties in India only the Monteverde (D132) seems in $2 range. Prices on Amazon India - Schmidt (SC51849) $ 4.5, Rotring (S0891230) $6.5, Zebra (4c) $6.5, Uni (SXR-200) $8, Platinum (BSP-100S) $12, Staedtler (92RE) $17.5!! Absolutely ridiculous robbery by Indian retailers. But still waiting to give the much touted hybrid Zebra Emulsion (RESB7) a try. At $14 equivalent on Amazon India my conscience doesn't permit.
