It is safe and delicious

HOW TO USE
1. Freeze the cleaned blur for at least 12 hours on the coldest side of the freezer.
(The longer you freeze, the better)
2. Keep cool drinks in beverage, milk, fruit juice, vegetable juice, etc. in the fridge.
3. Pour enough frozen blur into the cup and pour the cooler stored in the fridge into the blur (only 60 ~ 80% Please) about 250ML

Add the beverage and stir for about 3-5 minutes with a spoon.
If you have a lump of ice, just remove the lumps attached to the wall of the cup and stir it gently as you mix it with your drink.
Enjoy the delicious slush!
