ACELY36 Pieces Bottle Pack Fountain Pen Ink Cartridges Refills – Short International Standard Size - (Black Ink + Blue Ink), PH-100

Seems like so many cartridges are too long but this is almost identical - there is a slight difference in the shoulder area. The Mont Blanc cartridge is on the right and the new one on the left. Little bottle is cute but you will need tweezers to get that first one out. Ink is smooth and dark so I'd say this is a good buy.

You get a lot of ink with this and I love the bottles but I just wish they were glass. Otherwise it’s a good deal.

Fits good and snug and writes beautifully.

The ink is good and would be better if I received the two bottles I should've received.

Clogs my pen frequently.

I ordered this and when it arrived the black ink cartridges all had holes and leaked. I sent them back and ordered another set. Same exact problem! Black cartridges all leaked. How on earth does that even happen? And twice?!!?

I've switched mostly to fountain pens as they help with carpal tunnel and arthritis issues so I go through A LOT of ink. These little refills are excellent. They aren't messy and come in little plastic jars that keep them fresh and well contained. They pop right in to my pen and after a shake or two, the ink flows beautifully. Highly recommend! :)

Always good to have extra on hand. Currently using in my Amazon Basics fountain pen.Worth the money.I've using this in my Amazon Basics fountain pen, writes quite nicely.
