Pen saved to write another day!
I have many pens that have run out of ink and have saved them with plans to buy refills. I finally went to Staples and the manager helped me sort through many packages to find just the right one. It is a joy to have my favorite pen back in service again. Thank you!

I haven't used this product yet so I can't give an evaluation. Apparently Staples policy thinks a product is used immediately upon purchase.

Refills for my favorite pen. I’ve had it for years and will not give it up willingly. Smooth and clear without smudges.

I had a hard time finding these refills. Staples had them. I will make a note with my center of gravity pen now to go there first next time I need something.
