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.
Q: What is the shade of the blue-black ink?
A: The ink is a classic deep blue-black shade, suitable for formal schoolwork and official documents where black ink is required but a slight blue hue is acceptable.
Q: Is the ink safe for children to use?
A: Yes, the ink is non-toxic and safe for elementary school students. However, it is intended for writing purposes only and should not be ingested.
Q: Are these cartridges compatible with erasable fountain pens?
A: No, these are specifically non-heat erasable ink cartridges designed for permanent writing. They will not erase with friction or heat.
Q: Will this fit the older version of the Dian Shi pen?
A: These are designed specifically for the Press-Type Fountain Pen Special (Model 1784). Please check your pen model number to ensure compatibility with older versions.
Q: How many cartridges come in one package?
A: Each package contains 6 individual ink cartridges.
