All parts were numbered. Received duplicates of one number, none of others. Had to use the duplicates, but because they weren’t the right part, had to drill own holes. Screws were nice and sharp that this wasn’t too hard, but some of the supports for the shelves splintered. Thankfully they were the middle supports so the shelves should still hold. Overall easy enough to put together. If you buy, the staples go in the inside!
