6X Blue Cross 8513 Compatible Ballpoint Pen Refills, Medium Tip Ballpen

They work

Great quality and an amazing deep/purple blue. It's great. I highly recommend it.

VERY GOOD

The fact that it’s more than half the price for the same thing that’s a named brand but it does the same job and there are 6 instead of one great I would purchase them again

These refills are not fit for purpose. Apparently compatible with Cross 8513; utter nonsense. Please see my photo: the one with the black plastic base is a genuine 8513. You will clearly note that not only is this repro junk not in the same basic dimensions, the 'refills' are not even the same size as each other! If you try using this no-quality junk in your pen to actually write, it will immediately start to retract and render it useless. If I have not been clear enough: do not waste your money on these unmerchantable refills!

Good value for money. Don’t know how long they will last as only used once so far!

Fantastic price compared to stationers

All the refills have leaked in the packet after a couple of months and are useless. Worth paying extra for the genuine item.
