"When your own greed punished you" is the name of my order. I chose 3.4 mm, so that it would be bigger. It turns out that this is the diameter of the capsule hole, and my pen needs smaller ones. So I should have ordered 2.6 mm. But this is not indicated anywhere on the pen... I had to manually fill the pen reservoir with a syringe. In short, money down the drain. Be more careful when placing an order. The ink itself is ordinary, blue, on white 80g paper it spreads a little, but maybe this is the fault of the pen, not the ink, I don't understand. All 50 pieces were put in the package. The order arrived on time.

This time the size was suitable for a regular ink pen. However, there was no box, all the cartridges were simply poured into a bag.
