Pelikan4001 GTP/5 Ink Cartridges for Fountain Pens, Brilliant Black, 1.4ml, 5 Pack (310615)

These ink cartridges fit my Muji Aluminum fountain pen perfectly. The ink quality has been good thus far.

I just found this pen after it sat in a box of university supplies for >25 years. The only ink cartridges I also found in the box did not fit that pen, which is a head scratcher. These Pelikan cartridges are perfect and this pen writes like it is brand new again. I only wish this ink was waterproof, but I plan to get a Pelikan converter now that I know it will fit and use that with some waterproof ink.

See also other review for the Black. These can be used in any pen that takes a Waterman fountain pen cartridge, but not where a short version is used. They cost less, but provide the same amount of ink. I bought elsewhere a 15 pack, i.e., 3 5 pack ones sold together. Longer lasting than the shorter ones.

Everything about this order was as expected and arrived on time.

They work great in my Pelikan pen.

Have been using this for years in fountain pen. Have used other colors but those cartridges are smaller and don't last as long. Can't say for sure exactly how long each cartridge lasts. Use to write letters and journal entries. So not an every day pen cartridge. But re-order infrequently because they last so long.And the ink flows smoothly from the tip of your pen. If have good penmanship can write just like days of old. Wish kept up that penmanship learned.Perfect for any fountain pen that fits this style cartridge. Highly recommend.

So happy these actually fit my Duke 600fude pen which uses generous amounts of ink.

The color is pleasant to look at. Ink does not bleed all over the page. This ink cartridge does what it’s supposed to do. It is the best it can be. I don’t think manufacturer can do anything to improve it. No complaints from me.
