Two sets of shelves available. Each is made up of two “L” shaped units, with 3 12×12in openings and one 20.5×12in opening. The large opening has a back with a grommet meant for cords. You can play with how you put the two together. 16" deep, 47" across.
For what it’s worth, I have loved these shelves but they don’t work in my new apartment.
$100 each set, 2 sets available.
