Adonde played with the proportions of their MW magazine rack to come up with this paper/holder.
They lowered the height and added and extra wave - hence the name Mww -- to make it easy to handle and practical as a desktop element.
There are two parallel waves of metal wire. The first wave is lower than the second wave so we can put papers and documents according to size.
The waves meet in the front and at the back. It is indeed one single metal wire that holds papers and documents as a silhouette of a structure - two full waves.
