Dr. Grip 4+1 Multi-Function Ballpoint Ink Refills, Fine Point, Black/Red/Blue/Green Inks, 4-Pack (77154)

Exactly what I needed! My favorite pen is a pink Dr.Grip 4+1 that I got in Japan, and it writes impossibly smooth. Loved it, til I ran out of ink, and I was distraught! Little did I know this refill exists, and it fits perfectly, and writes just as smooth as the original ink! Satisfied customer :) recommend the ink and the pen!

This pen is perfect with the different color options and a pencil. Bought it because of its thick barrel, which helps me hold it with my arthritis.

Y’all! This pen is amazing! First of all, I’m obsessed with pens, they’re amazing and if you haven’t had a moment where you use a really nice pen and fall in love you’re lying to yourself! Anyway, I judge pens on how they feel when writing firstly, and this pen writes really well! All of the colors do! It doesn’t bleed, it’s not super thick lines but also easily readable! The colors are really nice! But the BIGGEST thing I absolutely love is the fact that there is a mechanical pencil added in! Like it’s one thing to have multiple pen colors in one but to also have a pencil option pushes it over the edge for me! Yes it was expensive for one (technically more than one) pen, but if you’re like me and you love pens, or you’re just looking for a good quality pen with multiple options and actually hold on to your pens for awhile, then this is the pen for you!

Far superior than any other multicolor pen. I use this product daily in healthcare, school, and everyday life. Larger grip without being too bulky. Provides the multiple colors along with mechanical pencil AND eraser. This product does not allow for erasable ink, however it is far superior than any other variation you can find including the versions with erasable ink.

Pen functionality is top notch but ink durability is less , one of the color ink emptied so quick , and the replacement ink cartridges are very expensive though ..

Feels great to use and to write with. I have yet to refill the pen despite buying this in July with periodic heavy usage. I would recommend buying this pen at least once to try it.

Replacement ink. Easier to find here than in the store. Used to be, I'd go to a stationary store, but many of you probably don't know what that is, so Amazon is much easier! 👍🏻

was wondering how I could replace the pen cartridges without having to buy new pens. I love my pen
