This frame consists of two pieces of acrylic glass, four lists made of either untreated oak or aluminum, and a rubber band.
The rubber band both holds the frame together and serves for hanging the frame on your wall.
As you hang the frame from the rubber band, which goes all the way around the frame, you can hang it from all four sides
Clean the plexiglass of the frame with hot water and a soft cloth. The plexiglass also tolerates glass cleaner.
