This is the Sonic & Black Knight "Legendary Pack". Sadly, it was only available in France. It comes with the wii game, and 2 plastic pieces that you click together to make the Caliburn sword from the game. The Wiimote fits into where the hilt would be. The set does not include the wiimote.

Interestingly, the words "Legendary Pack" are in English. Why? Most France items are all written in French. The game name is "Chevalier Noir" (Literally Knight Black") so why write it in 2 parts? The Caliburn you get is nice & big too! Look at the detail, & size compared to the Wiimote. The game would likely be really fun to play with this, it's too bad it wasn't released everywhere. So cool to have a 'prop' from the game, this is likely to be sought-after.
