The very best is subjective.. BTW , one of the three , Parker and Mix are legendary brands with commendable pedigree and illustrious past .. Especially Parker , they developed the timeless 51 and contributed heavily within the evolution of fountain pens, Mix is another fine brand established in 1846, that being stated, a few of the modern choices from individuals brands aren’t up to the objective.. Outsourcing /licensing of production to 3rd parties and price cutting additionally towards the dealing demand to fountain pens responsible.
Pierre Cardin is an extremely different brand , they’re much more of a design house , a way statement , as opposed to a proper pen company,
They may have labelled some decent searching pens , but many are created by organizations and re badged to Pierre Cardin .. I will not count them as with exactly the same league of Parker , Lamy ,Sheaffer , Pilot etc..
For those who have a particular budget and needs , I am happy to enable you to suggest some nice models..
