Work bag designed to accommodate a laptop up to 15 inches and serve as a document carrier. It features handles for hand transport as well as an adjustable and removable shoulder strap made of recycled cotton webbing. The cotton used is recycled cotton and the added polyester comes from recycling PET plastic bottles. During the recycling process, tracers are added to the yarn, namely viscose and ceramic filaments that serve as a unique fingerprint. These tracers reflect light in a unique way and carry a unique and tamper-proof code, allowing all information from the processes the yarn has undergone to be stored in a blockchain. Aware™ tracer technology and the corresponding blockchain platform allow the end consumer to track the entire production process and ensure that the product has been recycled using its own waste, with no possible alterations. A special label with a QR code allows access to the Aware™ platform and direct authentication of certifications via a simple smartphone. Capacity: 8 liters. Dimensions: 38 cm x 7 cm x 27 cm. Composition: 70% cotton, 30% polyester.
