The Ghostbusters masks available are Slimer and Stay Puft. Slimer comes in purple packaging with the Ghostbusters logo and Slimer himself on the front. Stay Puft comes in a cool blue box with the Marshmallow giant also featured on the front.
Both Trick'r Treat masks are of Sam but you can either grab him masked or unmasked. Unlike the Ghostbusters packaging, the packaging this time is the same for both masks but it looks incredible. You can clearly see that the design is heavily inspired by vintage Halloween imagery and the boxes really do look fantastic. Each mask measures between 4-6 inches high and they are made from solf polyfoam.
