02 — Ink

The same word.
Endless ways to express it.

Ink is much more than the colour we leave on the page.

It can change the intensity of a word, create variations within a single stroke or reveal an unexpected sheen as it dries.

It also affects how your pen flows and how it feels to write.

And, most fascinating of all, you can transform the experience without changing pens. Sometimes all it takes is a different ink.

01 — COLOUR

How many blues are there?

One blue can be deep and elegant. Another, bright and vibrant. Some lean towards turquoise. Others have grey or violet undertones.

And the same goes for greens, reds, browns and blacks. Colour can completely change the personality of our words.

Classic tones

Blacks, blues and understated colours for elegant, versatile writing.

Expressive tones

Greens, turquoises, burgundies and vivid colours for writing with real personality.

Special tones

Unexpected combinations and nuances that invite you to experiment.

06 — The Writing Lab · Special experience

Your handwriting says a lot about you.

Because everyone’s handwriting is as unique as they are.

At The Writing Lab we explore writing instruments, but there’s something that makes them truly personal: the way you write.

Graphology invites us to look at the strokes, slant and size of our letters and explore what they might suggest about our personality.
