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 full-grain Tuscan leather, tanned with vegetable tannins. Its non-homogeneous appearance is the result of 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 fibres are released. The leather thus acquires those differences in colour tones, grain and softness, which make each piece of the Black Square collection unique and exclusive.
