With the Simba Glibbi Blubber bath bombs, bathing becomes a colorful experience. The set contains four colorful balls that fizz in the water and color it vibrantly. Each bath bomb exudes a fruity scent: apple, strawberry, grape, or tutti frutti provide variety in the bathtub. The bath bombs have been dermatologically tested by Dermatest and rated "Very Good". They offer a playful way to discover the element of water and stimulate the senses while bathing.
