PILOTDr. Grip 4+1 Multi-Function Ballpoint Ink Refills, Fine Point, Black/Red/Blue/Green Inks, 3 Pack

Love the functionality of it and the availability of refills, however I would recommend that the black ink in this model be available as a single option as well as with the multi color. The black ink gets used more than the other colors do.

I have a couple of Pilot 4+1 multi pens and bought these refills due to my experience with other multi-pens. The refills don't last long - partly because of the skinny size and partly because they are rarely filled more than halfway (low ink volume). I typically get a month's use (two at most) out of any multi-pen refill. These surprised me, however. I've been going so long on the original Pilot refills that I forgot how long I've been using them. It has been at least 6-8 months of daily use. That's exceptional to me.

These PILOT Dr. Grip 4+1 ink refills are my go-to for work journaling and note-taking. The fine point ensures precise writing, making my notes clear and professional. I’ve been using these pens for a while, and they never disappoint. The refills are easy to install and provide a smooth, consistent ink flow. Perfect for anyone who values quality writing instruments for their daily tasks.

An excellent refill. It works with Pilot's Dr. Grip Multi-pen and Uni Ball's Jetstream multi-pen.

I do a lot of annotation and explanatory diagrams, and have got myself in the habit of carrying and using 4+1 multicolor pens.The Dr. Grip body is my favorite on the market (and at this point I've tried 7 different options), and the Pilot refills are my second favorite. The Uni Style Fit system offers the second best body, and my favorite of the refills. Fortunately, the two are compatible with each other's refills.As much as I like the Uni Style Fit refills, these are substantially cheaper and longer lasting, and slightly less prone to smearing, but they give a little more drag when writing, and the colors aren't quite as vibrant. I've alternated on which I use. These are certainly fine to keep an Dr. Grip 4+1 in action.

Bought these refills at the time I bought my new 5-in-one pen/pencil. It was cheaper to buy the refills this way. Colors are true black, blue, red & green. Shipping was quick.

Work well.

Two of the refills in my Dr. Grip 4+1 finally petered out, and I decided to get the 3 pack of refills since it was a better value. The refills I received were genuine and fresh (dated April 2023 on the refills) and worked great.
