30 PCS Asvine Hongdian Fountain Pen Ink Cartridges 6 Colors Set（ Black, Blue, Green, Red, Purple, Light Blue, 3.4mm Bore Diameter

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.

Satisfied with price and quantity. Ink flows great, Good quality noncarbon ink that v writes like ballpoint pen. Drys fast.

Really easy to use. Ink is great color and saturation

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.

Works quite well for my pen.

This is my first fountain pen and I am very pleased with what was received. I purchased the medium tip based upon recommendations but I think I am going to try the fine point for comparison. The pen came in a sturdy metal container. Each pen has noticeable weight which gives it durability. Easy to set up and clean. I also picked up some refill cartridges so I have 29 more to go! It works out to around 32 cents per cartridge. Way cheaper than buying disposables.

The ink is great, kinda wish I just bought all black ink or the blackish green hong Dian sells but the quality of their ink has always been good to me

Did not fit any of my hongdian fountain pens!Update - you have to press really hard until you hear a click. The set did have dry cartridges which would not flow the ink.
