PIQUADRO, a global luxury brand from Italy, is driven by its strong dedication to its values for design, functionality and technology. Black Square accessories are made with a full-grain Tuscan leather, tanned with vegetable tannins. Its non-homogeneous appearance is the result of an original craftsmanship. After tanning, skilled hands lay the leather in large tanks full of water, without adding chemicals. The leather is then dried in the drums and finally stretched, so that its fibers are released. The leather thus acquires those differences in color tones, grain and softness, which make each piece of the Black Square collection unique and exclusive.
