The Barbie Girl device is basically an MP3 player with attitude. First, it offers a range of customizable fashions and accessories, delivering the next generation of fashion doll play. Second, it is a music device with 512 MB of on-board memory (able to hold about 120 MP3 or 240 WMA-file songs). Third, the Barbie Girl device acts as a "key" for girls who have a room on barbiegirls.com. Girls who have this device and who have physically connected them into one another’s computer docking stations can become "best friends" and chat in "secret." It adds a more personal touch to the site experience and an extra layer of safety for parents. The device comes with a secret code, as well, that once entered on the site can allow its user to unlock additional pets, games, hangouts, fashions, and more. To get additional secret codes, girls will have to buy more Barbie accessories, hunt them down on the Internet, or possibly ask their new online friends.

Barbie Girl Pink comes with two hairstyles, two faces, two tops, two skirts (one over pants), and a pair of shoes that can be interchanged to match the owner’s current mood and style. The tech gadget also includes adjustable earbuds, a belt clip, and a durable storage case so it’s easy to take everywhere. Additional packs of fashions, pets, and accessories are sold separately and offer the ability for girls to make their Barbie Girl as unique as themselves.
