This is a clear acrylic window for use with the Q-Pack Cyclotron's internal components from Ghostbusters: Afterlife. You should only purchase this part if you are building a "Q-Pack" or will be building one from scratch. Not compatible with the Hasbro Proton Pack.

The acrylic is clear and has a brown paper backing that will need to be removed (the photo shows the paper to make it easier to photograph).
