They were brand new hard drives in a large package, in plain white packaging (packaged by Toshiba apparently). For the price this is a great solution for my use. These are genuine Toshiba hard drives, but NOTE. They are covered by Toshiba's 2 year warranty but the 4 I received were manufactured in August 2014 so Toshiba's warranty has expired.
