PILOT Dr. Grip Center of Gravity Refillable & Retractable Ballpoint Pen, Medium Point, Charcoal Grip, Black Ink, Single Pen (36180)

I will not use another brand of pen after discovering these! The feel of the barrel in your grip is smooth, comfortable and functional. The design is clean, sharp - making it durable and able to withstand drops and even my dog thinking he can write as well. They write so smooth and the ink doesn't smudge. While the price isn't the cheapest on the market, they are worth every penny spent - I have purchased multiple to keep in different spots around the house, my purse, my travel writing bag, my desk and the fun part, you can purchase ink refills in different colors to change things up if you like! I currently have pink, burgundy, purple, blue and black and if I can find other color refills I will get them as well. I can't say enough good about this pen!

Best pen for lefties needing to take lots of notes! I’m a pen connoisseur, get so frustrated when my left hand smudges or my hand cramps up. While it’s not entirely smudge free, it’s minimal compared to other pens. It writes easily and the grip is fantastic. I’ve bought this pen probably a dozen times now (losing it, gifting it) this pen is truly the best.

I'm one of those people that LOVES pens and this pen is in my top ten favorites. I've purchased several of these pens and I love them. I love the squishy comfort grip, the weight of the pen, and how well it writes. These pens are well worth the money.

I'll cut to the chase, the Center of Gravity design is one of the most comfortable pen designs I've ever used, I write a lot and sometimes I'll get cramps and fatigue in my wrists or even fingers, with this pen I can keep going for longer sessions. In addition to the nice grip and balance design, the Pilot turbo ink is superb! If gel roller ink was described to be in between liquid ink and ball point... then I would describe this ink to be in between gel and ballpoint oil ink.. it is just so smooth+fluid(it just glides!), and it doesn't bleed through like gel and liquid ink has a tendency to. Having said this, I've bought refills for this pen and noticed that it wasn't as good as the refill it shipped with(this goes for the Full Black version, the cartridge that it came with wasn't as smooth as the one that came in the CoG, I swapped them and used them extensively to make sure I wasn't imagining it, hah.. I mean I could be wrong, but it is noticeable.. and having said that, the refills that I bought are still adequate and better compared to competition ball point pens out there.) I'm briefly comparing this ink to the original Dr. Grip (had it since the mid 96-97'), Fish Space pen(medium point), and Zebra F701(that's nice and smooth too, but a bit too light for my preference).

I’ve always loved these pens but have a hard time finding them in store. As expected, great quality, feel, and writing is a breeze!

It’s comfortable, however, you need to buy special ink replacements that are shorter than the normal pilot replacements you see in stores. You can’t even use the other “Dr. Grip” replacements, it has to be for this specific pen. You end up getting less ink at a time. That’s a big downside. Aside from that, I like the pen and it’s nice to write with. It’s very sturdy.

I really like how this pen writes. It doesn't require a lot of pressure and the inks flows well.

Comfortable to use, glides through paper. For me, it is worth the price.

Writes like a dream and the grip is steady and very comfortable. Nice to look at. I love pretty pens

Grip of this pen is really amazing.one of the smooothest grip, I have used.ink is also nice.pilot people really know how to make pen.

Pleased with pen. Good grip and smooth writing. I have bought it as a present for an elderly friend.

Es un bolígrafo cómodo que permite una buena escritura. El modelo que se vende en España, con mucho menor coste de envío

I don't see this pen in stores anymore, closest was Tokyu hands. So I was really happy when it saw it here, at a reasonable price. Bought one, and then the next day bought another.
