A stunning work of art for creating art

I was not expecting to fall in love with a pen so far from my usual favored brands. The body color is absolutely captivating, but ultimately the nib was what clinched it for me. Flexible, agile, fine tipped but splayed easily with very little pressure to create wider lines. It was a joy to write with and lended itself well to doodling. It made even my basic penmanship look good. I'm looking forward to many years of creating with this pen.
