Piquadro briefcase with wheels made of leather and equipped with a padded compartment for laptop 15.6 inches. Blue Square collection is the top of the brand, offering a huge range of products from small leather goods to business briefcases with every comfort; colors used are the typical black, blue, and mahogany, including more vibrant shades such as red and orange of women’s bags or organizers. Blue Square is made both for those who prefer an elegant and classic style and for those who want to look more modern and dynamic; every Piquadro product is created in chrome-tanned calfskin refined with aniline. This traditional tanning method maintains the beauty of the leather over years. The raw cut edges, hand-painted in bright blue, light up the business character of the collection, giving a recognizable distinctive element.
