Each BlackFly Bag is unique and one of a kind, made from up-cycled material or products sourced locally from Nairobi. The Kitenge fabric used in the bag originates from different parts of Africa. It is typically very colourful and bold, used for all kinds of clothing accessory type items. The leather part of the bag is up-cycled from Mitumba markets. Mitumba is a Swahili term, meaning "bundles", used to refer to plastic-wrapped packages of second hand clothing that makes its way to Kenya, donated by people in wealthy countries.
