Kakuno Fountain Pens have all the thoughtful details you would expect from a Japanese pen! These fountain pens are designed for serious beginners. Known for having a smooth flow. Indentation at the top of the cap makes it easy to grip for removal. The metal nib has a smiley face inscribed on it! Cute but also makes sure you always know which side should face upwards. The cap and body are a hexagon rather than round so it doesn't roll away when you set it down. The grip area is triangular for comfort and to help you hold the pen correctly.
They come with a black ink cartridge. Use the Namiki refill cartridges. The ink is dye based and water-resistant on most papers, but not waterproof.
