This item comes with pre-drilled holes. Unfortunately, the holes were not drilled in the correct places. As a result, one side panel is either crooked, doesn’t have all the screws in, or you have to drill new holes, which ruins the look. I’m sure that we could send it back, but we’ve already spent the time unboxing, bringing the pieces upstairs, and building it. Since it’s for closet storage, we will keep it, but very disappointed in the quality.
