Very cheap quality so make sure you have a matching furniture marker to “erase” any defects or mistakes you will inevitably make during assembly. The back of the bookcase (the part that you out all the nails in) should be wider or there should be guideholes. We did a lot of unnecessary damage to the backing because we thought it was lined up correctly but it wasn’t. It’s not a hard adjustment to do on their end and it would have made a big aesthetic difference. Hoping the mistakes aren’t as obvious once the bookcase is filled.
