Review: A good value - A good value for the price, I got them as replacements for some old pens I didn't want to throw away. Some I had to cut to size to the original shorter sizes, I could not replace just one for a pen that has a slightly larger ink tube. I have been using some of the pens already and they work fine, ink flows ok. All in all I am satisfied.

## Questions & Answers

**Q: Will these work for zebra pens ?**
A: Sorry I cannot confirm this definitively.  However, as long as the Zebra insert is straight and not tapered at any portion, it should be OK.  I would suggest you measure the zebra insert before ordering.  The description calls out the length as: 
10.7 cm/ 4.2 inches; Note: not suitable for pens that are too long. Must pay attention to product size.
I actually had to insert something to increase the length for my purposes.

**Q: I did  not receive this even though it says I did**
A: They did not meet my satisfaction. 
They leak .write rough, and are scratchy.

**Q: do these work with the resin pen molds that show 4.3 inch pens with the molds?**
A: '
They didn't work with any of my pens, the shoulder is not large enough

**Q: What is distance between tip of pen and bulb(shoulder?)**
A: As I wrote in my review, that tip-to-shoulder distance is about 1.1 inch.  However, the amount of ink in these refills is less than the original in my Office Depot Super Comfort Grip Retractable Ballpoint Pens.
