Unfinished Freestanding Wood Corner Shelf (63" high)

Bought this several years ago but never got around to finishing it. No clue where the screws are (sorry), but it's easy enough to pick up a box of screws from Home Depot (or Lowes). Exchange will be in Redmond (no exceptions). Approximate measurements: * 63 inches high * 19.5 inches deep (and wide) * Shelves are 18, 15.5, 13, 10.5, and 9 inches Thank you for looking at our ad(s).
