What do you get when two Corona’s get together? Little baby girl Corona’s, or “Coronita’s” to be exact, cute huh! lol 
I’ve photographed them here beside a standard Red Bull can so you can see how small they are.
— US 7fl oz. is 207ml in metric.
The literal translation of “Coronita” from the Español is “Little Corona”. The suffix “-ita” is the feminine diminutive (the masculine is “-ito”) and is used to express smallness or affection/endearment. They also have big (945ml / Swappa Crate size) Corona’s over here, but there doesn’t appear to be an opposite to “ita/ito” so they are just called “Corona” like standard 330ml bottles.
