Perfect for my third grader
These cartridges fit our school fountain pens perfectly. The blue-black color is exactly what the teachers require, and the ink flows smoothly without blotting. Great value for a 200-pack.

Good quality, great price
Bought these for calligraphy practice sessions. The ink density is consistent, though occasionally one cartridge in a batch feels slightly lighter. Overall, an excellent bulk buy for students.

Standard fit works well
The 3.4mm size is truly universal for our collection of student pens. The carbon ink dries quickly on standard notebook paper, which helps prevent smudging for left-handed writers.

No more leaks!
My son used to struggle with leaking refills from other brands. These Hemu cartridges seal tightly and have never leaked in his pencil case. Highly recommend for elementary users.

Solid choice for schools
Purchased for our homeschool co-op. The color is a nice traditional blue-black, not too dark but very legible. One star off only because the packaging was slightly crushed upon arrival, but the cartridges were fine.

Lasts all semester
With 200 cartridges, this pack easily lasts two kids through the entire school year. The ink doesn't fade on the page, making it perfect for keeping neat notebooks.
Q: Do these fit Parker-style pens?
A: These cartridges are designed for the 3.4mm Standard International size. They fit most European-style student fountain pens but may not fit proprietary Parker converters or cartridges without an adapter.
Q: Is this ink safe for young children?
A: Yes, the ink is certified non-toxic and safe for use by elementary school children. However, as with all writing instruments, it is intended for writing on paper and should not be ingested.
Q: Can I use these in a pen with a converter?
A: Yes, if your fountain pen accepts standard 3.4mm international cartridges, you can insert these directly. If your pen only uses a converter, you would need to empty the cartridge into the converter, which is not recommended due to mess.
Q: Is the ink washable if it gets on clothes?
A: While the ink is non-toxic and water-based, it is formulated as 'carbon ink' for permanence on paper. We recommend treating stains immediately with cold water, but complete removal from fabric is not guaranteed.
Q: What is the expiration date on these?
A: Our ink cartridges typically have a shelf life of 3 years from the manufacturing date when stored in a cool, dry place away from direct sunlight. Please check the batch code on the box for specific details.
