No more messy eraser shavings

This is a game changer for homework time. No more rubber shavings all over the desk. The posture correction grip is subtle but effective for young hands.

Good quality pen

The build quality feels sturdy enough for a child. The eraser cap fits securely. Just remember not to use this for official documents as the ink can disappear with heat.

Excellent value set

Comes with extra cartridges which is nice. The crystal blue color is very pleasing and not too dark. Highly recommend for elementary school students learning cursive or print.

Perfect for my third grader!

My daughter loves this pen. The ability to erase mistakes by rubbing makes her much less anxious about handwriting practice. The blue ink is vibrant and the grip helps her hold it correctly.

Bought this for my classroom. Students are excited to use them, and it encourages them to practice writing without fear of making permanent mistakes. Very satisfied.

Great concept, smooth writing

The friction eraser works like magic. Writing is very smooth. I deducted one star because the ink can fade slightly if left in a hot car, but that is expected with heat-sensitive ink.

5 FAQ

Q: Is this pen suitable for left-handed children?

A: Absolutely! The ergonomic grip design supports proper posture for both left and right-handed users, and the friction eraser works equally well for both.

Q: Are the ink cartridges standard size?

A: The Chuanren 612M uses standard international short ink cartridges, which are widely available and easy to replace.

Q: How many cartridges come in the box?

A: The package includes the pen itself, the specialized eraser cap, and three replacement Crystal Blue ink cartridges to get you started.

Q: Does the ink completely disappear when erased?

A: Yes, the heat-sensitive friction eraser makes the ink invisible when rubbed vigorously. Please note the ink may reappear if exposed to extreme cold temperatures.

Q: Can I use this pen for signing legal documents?

A: We do not recommend using heat-sensitive erasable pens for legal, financial, or permanent records, as the ink can be altered by heat sources.
