Retractable Ballpoint Pen Refills 30 Pieces 1mm, Medium Point 4.2 Inch Black Ink Refills Smooth Writing for Click Pens

Fit perfectly and worked great, medium point and good ink flow.

The pen refills are good. Each has a protective ball cap to be removed before use. Remember to reuse the old spring as the refills are not supplied with springs.

I was hoping to find re fills for my favorite pens. So happy to have found the right size and smooth writing.

The refill was a bit shorter than what I needed, but it was the best size for my pen that I was able to find. I was able to improvise & add some length to the refill & now my pens work perfectly.

1mm size writes very well. The 0.7 mm said to be 'medium,' is actually too fine. The price for 50 is fair. Fits standard top click ball point pens. Ink doesn't smear or run.

Refills fit most standard length pens but need to check specific measurements to ensure proper size. Some of the refills appeared to be a little dried out but overall I was able to use the product.

I’ve been looking for an ink refill for a disposable pen that my husband loves and has nostalgic value to him. It’s been tough because the typical refill similar to this one doesn’t have the bump in the correct location. It’s been frustrating and I almost gave up. These fit perfectly!!! The pen was a disposable twist style pen. And it now lives on!

The fit is perfect and the ink flows well so far.
