This is what they have said when someone has asked if it's vegan:
"Sangkaya is NOT a dairy-free ice cream. There are little percentage quantities of condensed milk and evaporated milk"
But it says in their website: " The health-conscious and vegans are now entitled to enjoy real ice cream too."
It turns out that the contradiction stems from their total misunderstanding of vegetarianism and veganism. :/ Very careless for a place like theirs. They have been informed of it now.
