PentelEnerGel® Liquid Gel Pen Refills, Needle Point, 0.5 mm, Blue Ink, Pack Of 2

"¡Excelente tinta de recarga. Escribir con esta tinta es suave y fluido, sin manchas ni derrames. Me encanta que sea de larga duración y que mantenga la misma calidad desde el primer día.

I have recently discovered through trial and error that the Monteverde G23 and Pentel Energel refills, and therefore probably the Schmidt 888 as well, will work perfectly in 1 particular model of CROSS ROLLERBALL: the "X" models (which come in 4 plain colors + StarWars + Marvel design variations).They also can work, albeit somewhat tightly/short, in some of the CROSS "CLASSIC CENTURY" matte finish rollerballs, but NOT the Gold ones, in my experience. The refill tips do not come out as far in these though.They definitely do NOT work in CROSS TOWNSEND, SAUVAGE, or CALAIS models.I prefer the MEDIUM points (0.7mm), but that is a personal preference - they also come in FINE (0.5mm).The Monteverde and Pentel refills come in 10-12 ink colors.The PENTELs are by far the cheapest, in boxes of 12 for ~ $12. The MONTEVERDE's tend to go 5 refills for $11-12 ON Amazon, so over twice the unit price, but still far less than the CROSS refills, which also only come in 4 colors. I've only had the Pentels for a couple days, but they both seem to write ALMOST as smoothly as the CROSS refills that cost $6.75-7.75 a piece! I haven’t had long enough to see how long they last comparatively. But at that cost differential, the Pentels are a bargain and 1 box may save you enough to pay for 2-4 new X or CLASSIC CENTURY pens!But take note that the Cross "X" is a VERY WIDE GIRTH, CAPLESS/RETRACTABLE rollerball, so might not be ideal for all users. Those with smaller fingers might prefer to try in one of the CROSS CLASSIC CENTURY models, which also come in multiple colors. I have NOT tried in the newer "CENTURY II" designs.

I go through lots of pens, so was delighted to find these refills for what are favorite pens. They’re easy to switch and work well with no problem. Just don’t forget to remove the protective nub on the end like I did initially. Ha

I love the price of these refills. They are affordable and I get to use my favorite pen forever now.Some pros:The price is great. A little over $1.Quick shipping by Amazon - reliableEven when the ink is running low, it doesn’t skip. It just gets a little lighter.Cons:Maybe I just write a lot, but I feel like these run out of ink quickly. In 3 months I used almost two refills.For the price, can’t be beat

I had a Pentel EnerGel pen with 0.7 mm line. While I like bolder lines, I decided for everyday use a finer line would be better so I purchased these 0.5mm refills. Plus I'm assuming the ink reservoir should last longer as you're not using as much ink for finer lines. Took off the ball seal, put it into the pen and it works great, writes smoothly and the pen is still comfortable.

These Energels are pretty much my favorite pens so I was thrilled to find the refills. They don’t take up much storage space so I can keep plenty on hand. They’re also a heck of a lot cheaper and less wasteful than just replacing the whole pens every time I go through ‘em.Zero complaints from me on this - they’re the real deal and will bring back that smooth, lovely writing.

I have two Pentel Energel Gel Ink 0.7 mm pens that had recently run out of ink. One is stamped, "Metal Tip" and the other is stamped "Needle Tip". I purchased the metal tip refills and was delighted to see that it fit in both pens! The savings in purchasing refills is considerable, compared to buying another pen (only $1.22 per refill). Too much goes into land fill and this is a sturdy pen so why not reuse it as much as possible? Because I carry a Pentel Energel pen with me everywhere and have done so for at least two years, if not more, I know that this pen is built to last. Having purchased the refill before, I also knew that the refills are well wrapped and will not dry out. Therefore, I ordered 15 refills. There weren't enough on hand for a single shipment, thus my order was sent in batches (1, 2, 2, 2, 8) without extra charge until the order was complete within roughly three weeks. The pens write fluidly, beautifully, and without blotching. Now I can continue to carry a Pentel Energel pen with me everywhere and always have a spare. As a list-maker and 'ideas' person, I cannot imagine being without this pen! The ink colors available are: black, blue, red, violet and green.http://www.amazon.com/Pentel-EnerGel-Millimeter-Assorted-BL77BP6M/dp/B0012G9VNS/ref=sr_1_3?ie=UTF8&qid=1296929223&sr=8-3
