i would really like to replace the nib of my Elegante to something better..make it from a fine to a medium..so i was wondering - what size nib should i look for? and any online retailer that sells some good indian nibs i can buy from? i like my nibs buttery smooth..replacement nibs dont Have to be indian , anything good available online would do,,...but not from ebay as i dont have international credit card.....and thanks for your time..
