Runa Grigio Chiaro

Product overview

Strong at sight,
gentle at touch

Runa collection brings the essence of the noble and sophisticated character of the slates found in the countryside, villages and historical cities of Northern Europe. Stones that blend harmoniously with the elements of nature in a very contemporary style.

Nexion worked to recreate the taste of those suggestive slates that blend naturally in the architectural works of contemporary urban contexts. By the perfection of design and the hands of skilled craftsmen, Nexion has given to the surface of Runa the character of the best natural stones, strong at sight and gentle at touch.

Runa is a ceramic collection that returns the sober and harmonious elegance of slates with a modern and dynamic mood.
