The unit comes in a large brown box that's a fair bit larger than the actual NAS that sits in it. A simple label on the front displays which version of the TS3210DN is in the box and apart from a few shipping icons the box is devoid of any other markings.
The box bundle is pretty sparse but everything you need to get started is there; power cable, LAN cable, a pair of drive bay lock keys, Quick Setup guide and a warranty statement.
