Well, PRIME themselves have now publicly announced the bottle on their social media accounts. They have also confirmed that the bottle will be exclusively available in Toronto, Canada - and can be found in these stores: 7-Eleven, Circle K, Shell, Parkland and Petro-Canada.

It has also been confirmed that the flavour of the PRIME is that of Blue Raspberry. The bottle itself is a dark blue colour with a white lid and white detailing. The logo features the familiar PRIME logo but with an inflated R. It features both Auston's name on the bottle as well as a badge that says "AM34" - which is his initials and his number.
