Lamp arrives in a small rectangular box, so once you open there is some assembly involved but nothing major. 
Install was very basic, typical hanging lamp install. It arrives with everything necessary for the install and of course you will need the help of a second person once you start attaching it to the ceiling. It was nice that they sent the white candle stick option and black candlestick option because that can definitely make a big difference in how the room is styled. I don’t recommend this size for large rooms as it is on the smaller size but overall it is well made and exactly as I imagined these lamps to be.
