Replacement fountain pen nib for The Studio fountain pen. 14 carat gold plated with a hard-wearing iridium tip.

Architect - a double broad nib which forms a broad cross-stroke (approximately 1.2mm) and a thin down-stroke (approximately 0.3mm). Can also be used upside down for a super-fine hairline stroke.  

Cursive Italic - a specialised nib designed to produce a broad down-stroke (approximately 1mm) and a thin horizontal stroke (approximately 0.2mm). 

Fine - a springy, smooth nib with a slight flex. 

Medium - a firm, consistent nib for everyday writing. 

Semi Flex - offers a smooth writing experience with minimal upkeep and flexes from 0.5mm to 1.5mm, allowing for expressive line variations.

Japanese Brush Tip - perfect for expressive modern calligraphy, it delivers a bold 4.5mm line at its thickest, and a delicate hairline at its thinnest. Reversible, so when it wears down, simply flip it over and use the other end.
