Perfect for my third grader!

These cartridges are a lifesaver. My son is just learning cursive and makes many mistakes. The erasable feature allows him to correct his work neatly without tearing the paper. The fit in his M&G pen is perfect.

Great for practicing grip

The teacher recommended these for students practicing correct grip techniques. The ink dries quickly enough to prevent smudging but is still easily erasable. A fantastic tool for building confidence in writing.

No more leaks!

We have tried several brands, but these capsules seal tightly and do not leak in the pencil case. The 3.4mm bore fits standard student pens perfectly. Highly recommend for parents of young writers.

Good value, smooth writing

Bought the multi-color pack for my daughter's school projects. The ink flows very smoothly and the colors are vibrant. The blue-black is particularly nice for formal homework assignments. Only wish they came in larger packs.

Solid everyday ink

These work well for daily school use. The black is deep and dark, making it easy to read. The erasing function works best with a dedicated friction eraser, which is good to know. Good quality for the price.

Teacher approved

As an elementary school teacher, I recommend these to all my Grade 3 parents. They reduce the frustration of making mistakes and encourage students to keep practicing. The pure blue color is very distinct and pleasant.

5 FAQ

Q: Is the ink truly erasable with a regular rubber eraser?

A: No, this ink requires heat friction to erase. It is designed to be used with a specialized friction eraser (often found on the cap of compatible pens). A standard rubber eraser will not remove the ink effectively and may smear it.

Q: Does the 'Ink Blue' color look too light for grading papers?

A: The 'Ink Blue' is formulated to be distinct yet readable. While it is slightly lighter than the 'Pure Blue' or 'Blue-Black' options, it is generally suitable for student practice and notes. For official grading where high contrast is required, we recommend the 'Blue-Black' or 'Black' varieties.

Q: Are these cartridges safe if a child accidentally ingests a small amount?

A: Our ink formula is non-toxic and meets safety standards for children's stationery. However, it is not intended for consumption. If ingestion occurs, please contact a medical professional or poison control center immediately for advice, though the risk is generally low due to the non-toxic formulation.

Q: How many cartridges come in one package?

A: Our standard packaging options vary by retailer, but the most common pack size for these erasable cartridges contains 20 units per color or a mixed assortment of 30 units. Please check the specific product listing details for the exact count.

Q: Will these cartridges fit a Lamy Safari pen?

A: These cartridges are designed specifically for the 3.4mm universal bore found in most student fountain pens, including M&G brands. While some Lamy models use a different proprietary converter system, these may not fit Lamy Safari pens without an adapter. Please check your pen's bore size before purchasing.
