Kings Custard by DIY or DIE - One Shot Flavor Concentrate.
It comes in original bottle.
 
Flavour Description: Kings Custard is Wayne's take on the traditional custard profile: thick rich vanilla, egg, dairy, and light butter, whipped up with a touch of butterscotch and caramel. It was developed to taste delicious and rich right off a shake, but it really comes alive after two weeks, and reaches full peak around 4-8 weeks. This is a flavor that is as delectable as it is smooth, transporting you to a time when recipes were a bit more simple and straightforward.
