02 — Ink

The same word.
Endless ways to express it.

Ink is much more than the color 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 the most fascinating part? You can transform the experience without changing pens. Sometimes all it takes is a different ink.

01 — COLOR

How many blues are there?

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

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

Classic tones

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

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 what makes them personal is 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.
