Imported from the legendary Mr. Simms Sweet Shoppe in England, this Ultra Sour Candy is not for the faint of heart. Coated in a mouth-puckering acid dust and packed with a lemon-flavoured core that hides an extremely sour centre, these sinister black sweets are a true test of your sour strength. If you're a thrill-seeking snack connoisseur, this one's your ultimate challenge.
