These are well built, unfinished bookshelves. They are packaged incredibly well—a box inside a bigger box, with corner protectors and bubble wrap between boxes. The size is spot on — we attached the shelves on top of unfinished 12” deep “upper” cabinets (we’re using the uppers as the base) from a large home improvement store, and they match in size well. The woods are different, but once painted white, they look like built-in bookshelves.
