Two-Way Mirrors are magical artifacts.
Description[]
Two-Way Mirrors are large enchanted mirrors. In pair, they can link up two locations, acting as videophones and, if permission is given, as portals. Magica De Spell was gifted a pair of Two-Way Mirrors by the Aluminati Charm School in 2020 in thanks for helping defeat Eris, and gave one of the two to Gladstone Gander, whom she eventually persuaded to keep it (despite his understandable concern that she would thus use his house as a way to get to Duckburg to enact Number One Dime-related schemes) by pointing out that to break it would mean seven years' bad luck.
Behind the scenes[]
Two-Way Mirrors appeared in the 2020 story Hidden Potential.
