• Extra Fine Semi-Flex - A beautiful extra fine fountain pen nib with flex! This is a great middle-ground between the Pro Flex and our classic fountain pen nib, with its smooth writing experience and minimal maintenance. By applying a little pressure the nib will flex from 0.5mm to 1.5mm.

• Pro Flex. Uses a Tachikawa G calligraphy nib so it is extremely fine and very flexible making it perfect for practicing calligraphy and illustration. The compromise is that all this lovely flex is made possible by a steel alloy that isn't resistant to moisture. This means that the nib will need replacing if it begins to corrode and is ideally taken out of the pen between uses (more than a few days).

• Cursive Italic Fountain Pen Nib -  A specialized nib that is designed to produce line variations in handwriting. It is a type of italic nib that has a smooth, rounded tip that is slightly flattened on the sides. This flattening creates two distinct writing surfaces: a broader downstroke (1mm(+-0.1)) and a thinner horizontal stroke (hairline - 0.2 mm).

• Architect Fountain Pen Nib - The opposite of the Italic nib, with a broad cross stroke and a thin down stroke. It's a BB (double broad), which means it has nice line variation and strokes around 1.2mm at it's thickest (horizontal) and 0.3mm on the downstroke. You can also use the nib upside down for a super fine hairline stroke.

Tom’s Studio nibs are designed to fit Tom’s Studio “The Studio” and “Studio Pocket” fountain pens.
