Smooth and reliable

I am a teacher and recommend these to parents. The non-erasable ink is great for formal assignments, and the smooth flow prevents hand fatigue during long writing sessions.

Good value, smooth writing

Bought these for my son's fountain pen. They are easy to install and write well. The only reason for 4 stars is that I wish the pack came with more cartridges.

Works as described

These are genuine replacements for the Model 1784 pen. The color is a nice deep blue-black. Installation was click-and-go, very simple for kids to do themselves.

Excellent replacement ink

The 'correct grip' feature really helps younger students hold the pen properly. The ink dries quickly on standard notebook paper and looks professional.

No more leaks!

We had issues with other brands leaking in this specific pen model, but these Dian Shi cartridges seal tightly and have never leaked in my child's backpack.

Perfect for my daughter's homework

These cartridges fit the Dian Shi press-type pen perfectly. The blue-black color is exactly what her school requires, and the ink flows very smoothly without skipping.
