Rubber Bag to be worn as a sling bag, a cross body bag, a shoulder bag or a backpack. Its geometry allows for expandability. The main body of the bag is made from a fully recyclable and highly flexible polyurethane rubber. The bottom of the bag is made from upcycled denim sourced in London. The main body is 3D printed, which significantly reduces material use when compared to traditional injection-moulding. Small deffects and punctuations in the prints are normal and unavoidable when 3D printing, they contribute to the aesthetic of the product.
