Zebra Oil-Based Ballpoint Pen Refill for Sharbo X, Minna, SL-F1, for Tia500, Workdash, Black Ink, 0.7mm Point (BR-8A-4C-BK)

I've purchased these a few times and they continue to be top quality and good value. Long lasting finish ensures reliable service (with regular cleaning) and the consistency of the material gives a great range of line widths at different pressures.

I love these nibs! The up and down strokes are beautiful using these nibs. The nibs are durable and they don't snag the paper like other nibs do. Plus, they clean up beautifully. I have used mine several times and it still looks brand new! I do use pen cleaner and rinse with warm water. I will definitely order again in the future. Thank you for the fast shipping too! It was greatly appreciated!

These nibs work well. While they feel stiff to the touch, they will bend some depending on the amount of pressure applied while drawing/writing with them.

These guys are superb! They are the smoothest, finest nibs I have ever used. Almost writes like a ballpoint. They are lovely to use and my go-to for letter writing from now on.

Had a different brand of this style, but love that zebra sells these ones in packs of ten. Overall a great cost to quantity ratio over the other ones. They work great for my pen and ink artwork. I didn't do a thorough examination, but they seemed to all be in great shape

The spines on these are like rock solid, the nibs have almost zero flex to them. I have no idea how manga artists use these without going straight through their paper. So they’re good if you need technical lines with little variation, but bad for expressive line work. Also, the belly has a hard time holding ink.

This truly is a five star product. I’m an illustrator and this nib, by far, is my most favorite to work with. I never thought I’d ever stray away from Hunt’s 513 nib, but I’ve been converted. I highly recommend this nib to other illustrators out there.

Fits and works my Wacom Inkling, so smooth
