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

Great quality as always

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!

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.

This is the smoothest ink! I'm a very happy repeat customer.

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

Used for work

Dr Grip pens are the best. I am left handed and love a bigger size pen.

I was worried I wouldn’t be able to find these refills since this is an older model but here they are. Although a bit pricey, they fit my pen well and I’m happy to have it back in use. These arrived in good shape and as expected.
