Solid value for the price

You get the pen and several cartridges in the box. The grip is comfortable for small hands. Erasing isn't instant magic, but it works well enough for daily school use.

Smooth writing experience

I bought this set for calligraphy practice. The 3.4mm nib provides a nice line width, and the thermal ink is surprisingly dark before you erase it. Very satisfied with the M&G quality.

Good but be careful with heat

The pen works as advertised. Just a note: don't leave these in a hot car or near a heater, or your writing might disappear! My son learned that the hard way. Great for school, just store carefully.

Great concept, ink flows well

The blue color is very vibrant and the pen writes smoothly. The only reason I didn't give 5 stars is that the erasing requires a bit of friction, so you have to rub firmly. Otherwise, excellent product for students.

Perfect for my 4th grader!

My daughter loves these pens. She makes mistakes often while practicing cursive, and being able to erase them by rubbing the back of the pen is a game changer. No more messy eraser crumbs on her homework.

No more wasted paper

As a teacher, I recommend these to parents all the time. It helps kids feel more confident writing because they know errors aren't permanent. The cartridges last a decent amount of time too.

5 FAQ

Q: Does the ink disappear completely when erased?

A: The ink becomes invisible when friction generates heat. While it disappears from view, please note that under extreme cold temperatures, faint traces may reappear, though this is rare in normal conditions.

Q: Can I buy just the refills without the pen?

A: Yes, we sell standalone packs of M&G heat-erasable ink cartridges compatible with this pen model. Please check our 'Refills' category.

Q: Can this ink be used on official documents?

A: We do not recommend using heat-erasable ink for legal, financial, or official documents that require permanent records, as the text can be altered by heat sources.

Q: Is the nib size suitable for left-handed writers?

A: Absolutely. The 3.4mm nib is designed to glide smoothly regardless of writing angle, making it excellent for both left and right-handed students.

Q: How many cartridges come in the starter set?

A: The standard starter set includes the fountain pen and 3 replaceable ink cartridges (2 Black, 1 Crystal Blue).
