The creators of Coraline sent out 50 handmade boxes to some of their favorite bloggers. Each box is unique and includes items from the movie.
#8 belongs to Knitty Blog and features a collection of horrifying tools.
#15 belongs to Lines and Colors and features a scrapbook.
#34 belongs to VampireFreaks (registration required) and features a skeletal hand.
#39 belongs to Halloweentown and features bugs' wings.
You can see the rest of the boxes I've found to date here.
