This beautiful, heart shaped sponge is a fun way to entice your lover and invigorate your pleasure. The Sweetheart Pulsabath has a built in vibrator that's totally adjustable from low to high. Try it in the bath or hot tub, just apply your favorite soap or lotion, turn on the vibrator and rub it lovingly on your darling. Let the waterproof Pulsabath float and watch it create its own mini bubbling, pulsating spa action. Try it dry for a relaxing yet stimulating massage. Its soft texture absorbs creams and lotions, allowing it to gently glide over your lover's skin. The sponge is 4½" X 4½" and requires two AA size batteries, not included. What a delightful bath sponge indeed!
