White Ikea Billy Bookcase in great condition. The only small issue is that I no longer have the dowels for one of the shelves (pictured), so you will need to buy four more at a hardware store.
This bookcase has been chock full of books for several years and I’ve had zero problems with it. No shelf sagging, no tipping.
Bookcase measures 85" tall and 28.5" wide. Includes 10 adjustable shelves.
