Butterfly can be considered as a reduction of the object wall hanger in two pieces: a metal bar/binary and a wood hanger that, thanks to its symmetric “butterfly” shape, does not need further elements to be fixed. The wood hanger has a passive and active role at the same time: it is” hanged” but it also “hangs”, it has a self- standing shape that characterize it both from a formal and functional point of view. The butterfly-hanger is s available in 4 different wood essences.
