Works but ink fades slowly
The cartridges fit well, but I noticed the erased marks take a few seconds to fully disappear compared to other brands. Still functional, just not instant.

No leaks!
I travel with my fountain pen often and these cartridges have never leaked in my bag. The seal is very secure. Highly recommend for travelers.

Good value pack
The ink flow is consistent and the color is a nice dark blue. I deducted one star only because the packaging was slightly crushed upon arrival, but the cartridges themselves were fine.

Solid everyday ink
Standard reliable ink for daily writing. The push-button mechanism on my pen engages perfectly with these bladders. Good product overall.

Perfect fit for my Dianshi pen
These cartridges slide in smoothly without any leaking. The erasable ink works exactly as advertised when used with the matching pen. Very happy with this purchase.

Great for students
My daughter uses these for her homework. Being able to erase mistakes cleanly without tearing the paper is a game changer. Will definitely buy again.
Q: Are these compatible with standard international size cartridges?
A: No, these are proprietary cartridges designed specifically for Dianshi Small Hatch and 784/1784 series push-button fountain pens. They are not compatible with standard international sizes.
Q: Can I refill these cartridges with bottled ink?
A: These cartridges are designed as single-use replaceable bladders. While technically possible to inject ink with a syringe, we do not recommend it as it may void the warranty and affect the erasable properties.
Q: Does the ink disappear completely when erased?
A: Yes, when used with the correct Dianshi erasable pen nib, the friction heat causes the ink to become transparent. Please note that extreme cold may cause the writing to reappear temporarily.
Q: How many pages can one cartridge write?
A: Depending on your writing style and nib size, one 1.2ml cartridge typically lasts for approximately 15 to 20 pages of continuous A4 writing.
Q: What colors are available for this model?
A: Currently, this specific model (784/1784) is manufactured in Non-Thermal Erasable Blue-Black. Other colors may be available in different product lines.
