Tom's Studio - Fountain Pen Nib - Architect B

Effortless big juicy lines make this my go-to for sketching and everyday use


Made exclusively for our fountain pens, all of my nibs are tipped with incredibly hard-wearing iridium for super smooth writing, and are plated in a 14k gold for a classically stunning look. As a bonus all nibs can be interchanged so you can easily write in different styles whenever it suits you.

Architect Fountain Pen Nib - This is the opposite of the Italic nib, with a broad cross stroke and a thin down stroke. It's my personal favourite - the effortless big juicy lines make it my go-to for sketching and everyday use. 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.

We aim to process your order within 1-3 working days. Please note that this increases to 1-4 working days for orders that include any personalisation, such as engraving.

Have I found the perfect pen?!

I’m an architect and pen-pencil obsessive. I’ve been searching for the perfect pen for several decades. I think I might have found it! Weight/balance, ease of use, action of nib - all excellent so far!


I love this nib if I want to get a more consistent outline


I love the fine nib for illustrative works


Beautiful nib. Writes like silk.

The best!

I love the pocket studio pen and the pro flex nib, so portable, makes projects simple and is a pleasure to use!
