PILOT Dr. Grip Center of Gravity Ballpoint Ink Refill, Medium Point, Blue Ink, 2-Pack (77272)

Great quality as always

Easy to install, smooth writing, and smooth ink flow!!

I would really love if these refills also came in a finer point. It fits my San-x Sentimental Circus Dr. Grip pen and I was unsure at first what refill but went by a search from the one it had, as I had used another refill and it did not fit. 2 is great, and I am happy to be able to purchase more here again. Love the dark smooth ink !!! As well as the pen I use it with!An update: I just ordered “ Pilot Acro Ink Refill for Dr. Grip G-Spec Black Ink (BRFN-10EF-B) 2 Set “ for “extra fine” point, from Amazon, it also says 6 x 1 x 0.01 it fits my pen!!! Yay! I have not yet used the extra fine point but did switch out to see that it fits. These refills have thicker barrels than the Dr. Grip ink refills I used in other pens that I mentioned previously/above. I’m love that they all work for me and the pens I love and use them in, as well that they are available here for purchase!

This is my fav refills for my fav pen. I have one pen just for my checkbook that i have had for years and when it finally ran out of ink i was devastated. Im so glad for amazon since i was able to find the refills where they arent sold anywhere in my area.

There are 2 similar pens from dr grip, they even look exactly the same, thicker round body and stylish finish with rubber ring for fingers.The fillers are different. I wasted 10 bucks once thinking I am buying the fillers for my older pen.The right name is center of gravity, and itr is a shorter body compared to the new one that has a different sized fillers.If you are still not sure, take the filler away and memorize its shape. This one looks slightly shorter and the new one longer.

Used for work

It was a perfect fit for my pen. I have been looking for one for a long time because I love using the Dr. Grip pens and pencils! I bought this one specifically for Dr. Grip Pure White pen. Considering this brand is pricey, I'm glad that the refills work well. The ink is smoother than the original but there is still smudging when writing but I'm not too mad about it because it's inevitable.

I love the Center of Gravity (see my review there), so I bought 6 of these to make sure I have ink even if the pen is discontinued. I'm impressed with the way this writes -- it's so very smooth and reliable for a quick check signing. I don't even have to scribble elsewhere to get the flow started.At first I didn't care for the broad line -- I generally prefer fine line ballpoints. However, my needle nose ballpoint kept skipping for days each time I signed a duplicate credit card slip. Center of Gravity doesn't have that problem. And gradually the bold line has grown on me. I can write very fast with this pen and still stay legible and even neat.I don't know why the blue is so much more expensive than the black. But since it's a ballpoint, I expect this to last a long time, so it should still be pretty economical.Definitely worth stocking up on.
