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.

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 :)
