Outus 12 Pieces Black Ink 1.0mm Medium Point Metal Ballpoint Refill Set for Retractable Pens

Really good quality for a low price - I was really pleased with these.

Fast delivery, fits properly inside the pen, it does its job, Thank you

Fits Parker pen Writes well

Writing and drawing are fine

I have used these to keep using a Cath Kidston Pen I was bought, fits perfectly and the pen twist mechanism works with these as well. These do NOT fit with the Swarovski pens, they require a smaller one in length even though the ball point is the same.

Received ball pen refills this afternoon. 'JUST' put 6 refills in 6 different pens and they seem to work fine. However, you must remember to remove tiny protective cover on the tip.

Have a few pens that take this type of refill and really like these. Excellent ink flow straight out of the box and enough to keep me going for some time.Fit my pens no problem and great replacement for the originals. Fits Parker pens and well worth the money. Recommend.

Really useful product that works well in several different brands of pen. Good price and great quality for that price.
