4.37'' Rollerball Pen Refills, Roller Ball Fine Point 0.5mm, German Ink Refill Pack of Replaceable Pen Refills Medium Point(6 Pack) (Black)

Just right for my New pen

Found these after several attempts for my Japanese roller ball. The refill was slow to deliver ink but now seems fine

Nice to be able to get these refills at good prices and delivered next day. There are so many to choose from as well.

Worked perfectly and means I have my favourite pen back!

I find the origial pen beautiful to write with... THis is the same specification and fit but in comparison is scratchy and uneven..SHame because there are a few in the pack but hoping the others will not be as inconsistant...

Great value for money.

Disappointingly poor. The protective wax ball on the nib of the refill doesn't come off easy. Once removed (in fragments) the pen is very scratchy and the ink doesn't flow particularly freely. The first refill out of the pack was basically unusable. The second one is barely passable. Didn't give me much hope for the remaining 4 in the pack.

First thing I saw was the label on the box "Made in China". Sigh, I thought I was buying refills made in Germany. So wait, did they ship ink from Germany to the other side of the world, make refills, then send them back again? What a waste.Colour is pleasing, but as other reviews have noticed the pens are very scratchy. I have a pen made of glass to dip in an ink well that makes less noise than this rollerball. I also found it frequently decides not to actually write, forcing me to redo the odd letter here and there.Can't speak for longevity as I've only been using them to take notes for a week but while I'm happy to be using this particular pen again, I'm not impressed with these refills and wouldn't buy them again.
