Good quality, fast shipping

The ink color is vibrant and the erasing mechanism works well with friction. I deducted one star because the packaging was slightly crushed, but the refills inside were fine.

Decent but dries fast

The erasability is great, but I feel like the ink dries up a bit faster than standard gel refills if you don't use the pen daily. Still usable though.

Smooth writing experience

No skipping or blobbing. The 0.5mm tip is perfect for detailed journaling. The eraser on the pen cap works flawlessly with these specific refills.

Great bulk pack

Buying in bulk saves money. The blue ink is a nice shade, not too dark. They fit snugly in the barrel without wobbling.

Student essential

I go through so much ink during exam season. These are a lifesaver because I can correct mistakes instantly. Highly recommend for college students.

Perfect for my notes!

These refills fit my Dianshi pen perfectly. The ink flows smoothly and erases cleanly without leaving ghost marks. Great value for the price.

5 FAQ

Q: Are these refills waterproof?

A: No, erasable gel ink is generally not waterproof. We recommend allowing the ink to dry completely before handling to prevent smudging.

Q: Is the tip size available in 0.7mm?

A: Currently, the DS-784 model is only manufactured with a 0.5mm tip size to ensure precision and compatibility with the specific pen mechanism.

Q: How many refills come in one package?

A: Each package contains 20 individual ink refills, offering a mix of black, blue, and red colors unless specified otherwise.

Q: Do these refills fit the original Pilot FriXion pens?

A: No, these DS-784 refills are specifically designed for Dianshi Time Capsule Click Pens and may not fit other brands like Pilot due to size differences.

Q: Can the erased ink reappear if left in a hot car?

A: Yes, erasable ink is heat-sensitive. If exposed to temperatures above 140°F (60°C), the erased text may become visible again. Please store in a cool place.
