The Pro-Flex nib is a professional-grade titanium Zebra G with a super fine point, offering fantastic results (it flexes from hairline to 2mm) but requires a light touch, which comes from many hours of practice with a more straightforward calligraphy pen. For this reason, we recommend the Pro-Flex for experienced calligraphers only. This nib also features a new ink delivery system, the feed, which is designed to stay in contact with the nib. It achieves this through an integrated 'leaf spring', allowing the feed to flex when the nib does. Most flex pens fail when the feed loses contact with the nib, but this innovation ensures a consistent ink flow. This clever feature also acts as a 'sump', storing excess ink and releasing it as needed when the nib requires it. If you're a fountain pen user looking to add a touch of flair to your writing, we suggest starting with the Semi-Flex or Titanium Flex nibs. These options will help you develop the necessary understanding and muscle memory before advancing to the Pro-Flex.
