These refills were great for the G2 pens that we had that had simply run out of ink.

The refills are easy to put in and just as nice to write with as the originals

I have to keep the Ultra Fine 0.38mm refills on hand out of necessity, though

Very good ink replacements/refills

These refills are perfect

These refills work great!

Great refills.

Really enjoyed being able to purchase the refill as opposed to throwing the pen out

Amazon sent two packages of the wrong ink refills, but the ones that were correct are great.

This is the best basic pen and the refills make it easy and cheaper to use over again.
