Coraline Button Box on sale at eBay?

There's a button box from Coraline's Other Mother on sale at eBay, although the description strikes me as a little strange:

By way of good luck and an error on the end of the Laika company I managed to receive TWO of these boxes so, with a mixture of greed and kindness, I am putting the second one here for someone else to enjoy.

You will reveive [sic] the button box and the envelope containing the letter from The Other Mother.

Thanks to the tipster.
