In Australia, the product is made by Cottees, and is called Ice Magic. Ice Magic comes in chocolate, mint chocolate and honeycomb chocolate flavours. It is not to be stored in a refrigerator as it may harden, and will not pour. If this should happen, however, the bottle can be microwaved (without the lid) or placed in hot water for a short time to return the contents to a desired pouring consistency.
The "shell" effect in Magic Shell is due to the presence of coconut oil and sunflower oil, both of which are highly saturated, which produces a chocolate mixture which is solid at higher temperatures than would otherwise be the case.
