Effortless big, juicy lines make this a go-to for sketching and everyday use. The Architect nib is the opposite of the Italic nib, featuring a broad cross stroke and a thin down stroke. This nib is a BB (double broad), delivering beautiful line variation with strokes measuring around 1.2mm at their thickest (horizontal) and 0.3mm on the downstroke. For even greater versatility, you can flip the nib upside down to create super fine hairline strokes. Made exclusively for Tom's fountain pens, all nibs are tipped with hard-wearing iridium for effortlessly smooth writing and are plated in 14k gold for a classic, elegant finish. Plus, every nib is interchangeable, allowing you to effortlessly switch styles whenever inspiration strikes.
