Wood corner shelves. They used to be part of a very expensive entertainment center. They are great for storage in corners. We used them for pictures and nick naks for years. They are both 72" tall x 25" wide (the top), 22" wide the rest of the way down x 16" deep. The shelves are 11" deep in the center.
They are pretty heavy and well made and look great.
Asking $100 obo for both shelves.
