Maruna specialises in upcycling. The company offers hand-made clothes, bags and jewellery from reclaimed materials. Maruna finds the beauty in unwanted items with no aesthetic appeal and shows them in a new light. Highlights include bags made from old skirts and jackets, as well as hats and scarfs made from old jumpers. Unique vintage garments can also be found at Maruna. The owner of the company frequently attends events promoting upcycling and creative re-use of waste, such as Poltwór or Kiermasz Twórczej Reanimacji Odpadów (Creative Re-use of Waste Fair).
