Asvine Fountain Pen Ink Cartridges Black Color, Set of 30 Refill Ink Cartridges, 3.4 mm Bore Diameter

Great ink flow. Ink doesn’t smear like other inks. Nice deep blue color

Good ink. Very dark and drys quickly. Would buy again.

Excellent ink for the price, easy to exchange cartridges and easy to store. Writes great.

This is great budget friendly ink that works well with all of the fountain pens sold by Asvine/Hongdian that I have tried. The ink is a dark rich black that writes well and flows well even on finer tips. My only complaint is that these ARE NOT international and will not take/fit other brands unless they accept a 3.4mm cartridge. The ink also has a longer drying time so be careful or smudges will occur. Again, for the price you can't beat these cartridges especially for daily use. Use thicker paper for better experience with less smear and bleed through.

My pen used black ink previously, so the yellow mixed with that and became light green for one cartridge worth of ink. After that is became dark yellow, almost brown, and gradually lightened over time as the remnants of the black ink left the pen. That isn't the ink's fault, just something to think about. Overall this is good ink that flows well and fits the 3.4mm fitting snugly.

As much as I like using different inks and using a converter, I have a few pocket sized pens that either don’t take converters or that do but barely hold any ink. So I wanted to get some cartridges just for every day use. I reserve my nicer inks for when I actually sit down at my home to write to journal to take notes. These work great as they’re inexpensive and they fit the pens that I have just fine and replacing them is a breeze. The ink is just fine for every day notetaking when you’re on the go. It’s nothing to write home about, but it gets the job done and the price is very reasonable for what you get.

Easy to refill on my Hongdian fountain pen ink cartridges. The cartridges are hte perfect size for the pen. Just pull out old cartridge and install new one. Just push down until it 'clicks' and you are done and ready to write. The ink comes in several colors, and is very smooth. Dries nicely on paper, but looks even better on higher quality paper that does not bleed to the other side.

Bought several boxes of this ink with the Hongdien pen (which I like and I thought the cartridges were proprietary). The ink is okay, has good color, can get a little cloggy in the pen, but my real issue with it is that it takes way too long to dry. I have tried to use in my planner and, unfortunately, have ended up with several smeared pages, not because I don't know how to use a fountain pen (I've used one daily for years), but because I assume the ink will perform well. Sadly, it really isn't of the highest quality. I will try to use it up but having notebooks in which several pages are smeared and unreadable is a waste of time and money. Won't buy again.

I bought these cartridges to use with my Hong Dian M2 fountain pen. Used a green cartridge first without problems. But when I wanted to use a light blue cartridge it would not click into the pen. I compared all the cartridge colours and discovered that the tops of the blue and light blue cartridges are different! The shape of the top is clearly different and there is a very slight difference in the height of the cartridges as well. This is clearly visible in the pictures. Obviously there was a problem with the production process. My pen came with a converter and I can transfer the ink, but I should not have to with cartridges that are meant to fit this specific brand and model pen. I won't buy them again.

Sinceramente ,crei que sería acuosa pero es consistente y colores definidos. Me ha gustado mucho aunque por otro lado debido a su especial boca y el tamaño que tiene, no hay más remedio que usarlos.

Buen artículo para la pluma fuerte

een vulpen die heel fijn schrijft en waar je vele kanten op kunt.
