30 PCS Jinhao Fountain Pen Ink Cartridges 6 Color Set（ Black, Blue, Apple Green, Purple, Red and Orange International Standard Size

these are ink cartridges ; they work well

These are International Standard (IS) cartridges, meaning 2.6mm fitting, and can be long or short. These are long. I ordered all black. I've had colours before - orange is good for art perhaps, but not great for letterwriting or shopping lists. These cartridges fit my Dikawen, Baoer, Jinhao, Duke, Moonman and Montblanc fountain pens. They also fit Herbin and Schneider rollerballs that accept cartridges. Montblanc cartridges are slightly fatter than I.S. so they can get stuck in some pens, but IS cartridges always fit Montblanc pens. There was resistance with the Dikawen. A tight fit. I stand the cartridge upright on a table, fit the nib unit in place and press it down on the cartridge. That's easier than doing it in the air. Hero - these cartridges fit regarding the 2.6mm fixing hole, and fit models such as 7031, 7035, but some pens are so thin they need Hero cartridges or converters. Platinum are proprietary - only their cartridges will fit their pens. Parker, Yiren and Aihao use 3.4mm fitting. One reviewer said the cartridges were tiny and that his Jinhao pens took big Parker cartridges. Nonsense. These are the longer IS cartridges of standard IS width. The reviewer is confused. I can't find anything wrong with these cartridges, and was pleasantly surprised that they were long, after reading dodgy reviews. I notice these cartridges are cheaper than others offered on Amazon. I'm ignoring the 25 in a bag ones which a lot of people, including me, can't pierce or start no matter how hard they are pushed.

Hard to open have to pop with a pen not by putting it inside my pen they are the correct size for my pens but when I swap my holder for a diff size nib n colour they have fell out onto my work and they do run out quickly but I would by them again and I love the colours

Great variety of strong colours, and the large cartridge size means they need to be changed less often. And you get lots for the price, very happy

Lovely colour options, and these would have been good value if they had worked. They seem to fit, but I've been unable to get a good ink flow for more than half a word. I've checked my pen and it works with another plain cartridge I had. Disappointed; I quite fancied jazzing up my writing with some colour!

What is there to say about a fountain pen cartridge? Well a surprising amount ... First of all, does it fit? These cartridges are described as 'International" size - but there are two international standards. What I regard as the "old" standard have a outside diameter of 4mm on the part that fits into the pen, the "newer" standard being tad over 5mm. Some pens designed for the old standard will accept the newer ones, but most won't - and the reverse is never true... so make sure you have the right ones! Once yu have seen the two together, you will have no difficulty telling them apart The new ones are (generally) larger overall - with an overall length of 50mm compared to 38mm, and thus hold a significant amount more ink. Having sorted that out, these Jinhao cartridges are definitely in the "new" category (is it that my "old" and "new" should be "Western" and "Eastern" - I don't know!). That brings us to "do they work" - most definitely YES - and very well. I pulled together a selection of pens of different makes that were compatible with this type of cartridge and popped a different colour in each. All six colours (Black, Blue, Red, Green, Purple and Orange) flowed beautifully in their respective pens - so assuming that they all have similar characteristics, this bodes well for them working well with pretty much any pens that you are likely to use them with. As they have lots of ink, and are unfortunately not compatible with my first choice pens, it is likely to be a long time before any of them run out... Any reservations? The only reservation I would have is that the orange is not a deep colour, and would not really be suitable for writing with a fine nib - the result would be difficult to read. It is very good for other applications though - even with a thicker nib - good for example for highlighting / underlining in books etc, where the colour is not deep enough to obstruct reading of the original text. In short then - make sure they fit, and enjoy them!

Despite what is stated in the product description, these are not international standard size and they do not fit either of my Jinhao fountain pens. The neck of the cartridge is too long and the ball does not pierce even when cartridge is fully inserted into pen.

Good quality
