The packaging is good quality, and interesting, showing a large image of the product inside.
At the back there is a list of its specifications in various languages, while at the side we get the brand name and slogan. The side shows of that this is a kind of sideways opening chest/wrap box.
Opened up we find the mouse in a protective cardboard wrap and a little congratulatory note from Mionix.
Included inside you get a quick start guide as well as a whole host of Mionix stickers which is cool.
The Mionix Castor has a 2m long braided cable with a gold plated USB connector.
