24 Pcs Retractable Black Gel Ink Refills, 0.7 mm Point Black Ink

Bought these to refill some pens I had and they fit perfectly for most standard sized refillable pens (I use these on a G7 pilot and they fit well). Color is good and you get a lot for the price. Thick tipped ink and writes very well with good precision. Highly recommend.

It took a couple of tries to find exactly the right fit.As refills for my favorite U-Brand pens. These are perfect! Work great!

Write smooth. Nice pen refills.

Good price, works great

Okay, I know this will be just a little nit-picky. However, the length of the barrel of these refills is just a tad shorter than the barrels of the original manufacturer pens. This means that the tip is not as far extended from the opening. It hasn't affected my writing; just enough to be noticeable. Like, "Huh, that's odd, why isn't the tip fully extended out of the pen?" I compared these refills to the original taken out and sure enough they are shorter. The ink flows smoothly and is not messy which are the most important things to me. It isn't short enough to impact writing. Would have been a five star review except for the length.

I’m hooked on gel pens and these refills are great to keep on hand. They fit perfectly and the wax over the top keeps them from drying out when in the box. Once in use, the ink dries quickly on the paper and doesn’t smear.

Too early to give a definitive answer. Seem ok, write smoothly. One of the refills leaked

I love the erasable ink. I like the ultra fine size. The new pens aren’t always made as well because they are trying to make them cheaper. I have the perfect pens with refills that work wonderfully.
