PILOTDr. Grip Center of Gravity Ballpoint Pen Refills, Medium Point, Black Ink, 3 Packs of 2 Refills (6 Refills Total)

They are great and saves buying the pen all the time.

Genuine Pilot refills, my favourite pen, better than LAMY. I highly rate the Dr. Grip centre of gravity pen, I use it daily for at least half an hour, it is a excellent writing instrument and I will carry on using it for many years.

The refills are for my Dr. Grip pens. I have several do I go through refills a lot. Always write smoothly & don’t skip ink. Easy to put into my pens. Always the brand I use.

These are the right size refills for my Dr. Grip frosted pens. These are the red packaged ( gravity ?) refills. They are smaller than the black packaged refills. Got to be careful of the size for these pens... they're not always clearly marked with the refill order number on the pen packaging. They write smoothly and evenly. These refills last quite a while and less trash left behind by reusing the pen with a refill! Thank you!

These weighted pens do work, my mom had a stroke and using this pen helps her to write

Turns out this model is too long for the pen I own, but, using the original pen cartridge as a template, I trimmed off the end of the new cartridge and "viola"....perfect fit. Adapt and overcome, right?

Love these pens and refills.

good refills, smooth writing , use everyday,
