Great pen, but costly refill
Great pen. Due to 1.0mm we get more ink flow. Only problem - The refill itself costs 60 rupees. The refill finishes quite fast too :)

It writes very bold in future it should come in many tip sizes so it would be good for note taking
Absolutely amazing pen just one thing to note is that it writes very blod it has a 1.0 mm tip 9f there would be more tip options it would be way better rest now also it is better

Useful
I want the refills. Blue. Under 500 inr. Please list it before my pen eaten by my son. He is looking for it after a straight 8 hour writing that leaves the pen without ink. Thick nib. Smooth and grippy.

Pen ink quality
It can't be used for normal writing. It's for thick writing to be used on cardboard etc.,
