Each cupcake features a fizzy Epsom salt base for soaking and a handmade sugar scrub icing topper. Simply remove the wrapper and drop in the tub. The base of the cupcake fizzes and softens bath water for moisturized skin while the icing topper dissolves at a slower rate and is great to use as a pedi scrub. Large bath cupcakes are the same size as real cupcakes (approximately 5 ounces).
