Jacques Herbin 12300T- A 50 ml Bottle of Cleaner for Every Fountain Pen and Rollerball pens (Packaging-Free Product - Zero Waste Objective) - Fast, Easy

If you like to have a lot of different colours, full size bottles can be a little too much ink. Cartridges are one option, but these smaller sized bottles are also a great choice, and the pricing means these are excellent value. The colour is beautiful - it's got a faded character with variation when you write that makes it easy on the eyes, stands out, and still looks professional. It's simply one of my favourite colours to use. I've used it in a number of pens now, from my Jinhao EF to a vintage Mont Blanc with a broad nib, and this is definitely one where I like going a little broader to enjoy the colour, although the ink works well in different sizes and has excellent flow. It is a slightly wet ink and it's not very waterproof, so you need to be a little careful, but it's a great ink and one of my favourites. It can be used in a number of different ways, from formal office settings to personal use because it's a very versatile shade.

Beautiful ink! I've switched to fountain pen for daily use because this stuff is so nice. Cheap pen, nice ink, good times. One of my favourite colours, nice and deep, doesn't fade, true violet colour.

Absolutely shocked how effective this is. It revived a pen from my grandfather from the 80s! I'd kept trying to fix it over the years, leaving it in hot water and rinsing thoroughly but nothing ever worked. Thank God I didn't bin it, because after soaking it for a couple hours (just for good measure) in this solution, it is now as good as new!! It writes incredibly smoothly now, it is simply a joy to use. Previously I would struggle to write even 3-4 words with it before it would dry out, even despite having loaded a brand new Faber Castell ink cartridge. HIGHLY recommended

A nice all-purpose fountain pen ink that appears to behave well in most fountain pens, but can feel a little 'dry' with the finer nibs, as seems common with many green inks. Drying time is about average. No sheen or shimmer but can have some shading depending on the nib used. I'd call the colour a medium green tending towards colours like Diamine Woodland Green but deeper than Kelly Green. There are brighter greens so it doesn't feel too gaudy but can be a nice colour for individualism. I have found that the thinner Chinese nibs do not always like the ink and may skip a little, but the addition of one really tiny drop of diluted washing up liquid in the converter can help the ink flow better - your experience may vary. Herbin inks are generally good quality with a nice colour range and even have shimmering inks if you're into those

I have owned a Parker Centennial Duofold for 30 yrs, which over the last 10yrs has had very little use. Every now and again I have dug it out in the hope that 'this clean' will finally make it a pleasure to write with again. Each time has had no effect. It still remained 'scratchy' with intermittent ink flow, meaning having to use the plunger to squeeze a little ink out, all god for 5 minutes and then same again. Now I do know the tricks to filling, especially leaving it nib down after filling for a while to let ink migrate to the nib, all to no avail. Came across this by mistake and thought why not. Now don't get me wrong, it is expensive, but not as expensive as the pen, or the cost of sending it away to be 'sorted', or to buy a replacement no matter how cheap. Anyway, bit the bullet even taking some of the reviews 'with a pinch of salt' as to it's effectiveness, but, wow is the only comment I can make. Left filled with fluid for an hour, cleaned with cold water, dried thoroughly then refilled and it really is like I remember when new. Beautifully smooth, no scratching (even with fine nib) consistent ink flow etc. I seriously doubt if Parker themselves could have serviced it better. So, in conclusion to me it is worth every penny and then some, would I use it on a 'cheaper' pen, definitely, as no matter how much a new pen will cost, this still works out cheaper. No to mention with a fountain pen there is a certain amount of 'bedding in' to your style of writing that you would have to go through again. Hope this helps, and yes I did buy it, it wasn't a freebie in exchange for a positive review :-)

Beautifully bright ink. I bought the violet one, and it's just a shade off of Cadbury purple, which is what I was hoping for. It applies nicely in a wash (no idea how it behaves in a fountain pen) with no bits in it or colour settling. The only downside is the shape of the bottle, which I thought was quite sturdy, but it could do with having a heavier bottom as I nearly knocked it over.

It's a beautiful colour, and it dries quite quickly with a fine nib. However, this has to be one of the worst bottle shapes out of any ink. I'd rather pay more for more for a 50-50ml, and with that a more convenient bottle shape for filling vacuum filler pens. Herbin Essential Line bottles are perfect for ever the largest piston and vacuum filler pens. Come on Herbin, the little bottles are cute but wholly impractical.

From the oldest fountain pen ink manufacturer this one does not disappoint. Beautiful smooth ink flow and great colour finish. Would certainly recommend.

This is another gem from J. Herbin stable. This purplish blue ink reminds me of a delicate flower ‘forget me not’. It’s flows really well specially creates dramatic “scriptscape” on a quality paper.

Excelente azul com tons profundos quase preto

A cor é magnífica, como nas fotos. Produtos Herbin não decepcionam.

落ち着いた雰囲気の緑色を探しており、まさに期待した通りの色でした！万年筆らしいインクの濃淡がまた良い味を出してくれます。 (気のせいかもしれませんが、書いた直後と乾いた後で色味が変わる気がします。) ビンの一部が窪んでペン置きになっているのもお気に入りポイントです。30mlを使い切れるか不明ですが、また買いたい品物です。

Item arrived promptly. Ink has a greenish tint rather than blue grey as described in some reviews
