Aisu is a brand of e-liquids by Zap! Juice and it’s a delicious range. Aisu is inspired by the Japanese dessert Kakigori which is a blend of shaved ice and flavoured syrup (think of a snow-cone but even better) because of this inspiration every Aisu flavour includes menthol for that cool, refreshing taste. Their most popular flavour is blue raspberry, an incredible accompaniment to their menthol hit.
