10 x Pack Black Ballpoint Pen Refills, Medium Size Tip 11.6cm, Cross 8513 Compatible, Ball Pen Ink Cartridges Fits Cross Ballpoint Pens for Smooth Writing (10)

Great value refills, fit perfect!

Unbranded but doing the job well. No idea how long each refill will last, but the first one is writing well. They are narrower than the 'official' CROSS Fine refills, so I guess they won't hold as much ink, but they fit my vintage Colibri ballpoint pen fine.

I will begin with the positive, and move on to the drawbacks.These refills were good. They get the job done and the price is cheap. I am satisfied as they are not blotchy, nor does the ink bubble. They are a step above the quality of other refills I have used that are this cheap.However, the ink is rather inconsistent. I have used three cartridges so far, and they were all like this. Straight out of the packet, they wrote VERY smoothly (better than my branded, expensive inks). This lasted for a side or two of A4, before it ran dry and I thought it had run out. It then got a second wind , where the ink ran quite smoothly but much thinner, also the colour was not as dark and clear as before. It continued like this until it suddenly got thick and dark again and then ran out only a half page after that.All three refills I have used so far behaved exactly like this.It ran out overall after only 15 pages of A4 , which is many times quicker than other cartridges I had used.The reason these remain competitive is based on their price.They are a fraction of the price of the more expensive ones I have used, for twice the amount of refills.Despite the fact that they run out twice as fast, I still find I am spending less on these. I will see if this remains cheaper in the long run , or whether it is more cost efficient to buy the more expensive ones that last longer.

As described by the seller. Arrived on time

These work ok but they take a bit to get going.They are metal which means you can not see how much ink you have left till you run out..But they do write reasonably well once you get the ink flowing.

Good price., good fit, good writing - what else do you need?

Use these quite a lot

These refills were a perfect fit and allowed us to renew a number of pens rather than bin them. Tha added plus of not having to search for a shop that sold this item.
