Master-Piece was built on a commitment to high quality and functional design, and their Protean Shoulder Bag is a testament to this. The main fabric is a glossy nylon satin used for its distinctive sheen and durability. The reverse side showcases a matte contrasting nylon that delivers both a visual and textural distinction from its glossier twin. The removable/adjustable straps allows you to adjust the bag as needed and the plethora of useful pockets aids this bag in becoming a firm wardrobe staple.
