Is a mask a party supply? What exactly do you do with it at a party? A flat paper mask doesn't really fit into any other category on the site though, and it IS sold at a party supply store so...here it goes. The mask features a nice realistic render of Sonic's foreward-facing face, though the breathing holes (partially in his eyes...) make it look somewhat odd. At right is what the masks look like in the package, it's a simple starry background, with an un-hole-filled version of the mask graphic. These are about 8 inches wide by 9 high.
