This is Instamp, a set of alphabetical rubber stamps and ink pads from Japanese designer Yuzo Azu.

Instamp is no typical set of stamps. Because each sans serif letterform has a slightly rounded, supple surface, it's responsive to different angles and levels of pressure.

The result is an infinite number of custom typefaces.

Press lightly for a simple letterforms...

...or harder for bold, calligraphic letters.

For such a small adjustment, the design yields a surprising amount of expressive potential.

It's a clever take on an age-old interface, one that mimics some new digital tools.

Like, for instance, the Apple Watch’s pressure sensitive screen, which will distinguish between light taps and hard presses.

The project was among the winners of a design showcase organized by Lexus.

Sadly, there’s no word yet on if or when you’ll be able to buy the stamps.
