The vibrating love balls from the Sweet Smile collection are perfect to train your pelvic floor muscles and at the same time provide a great stimulation. The love balls have a soft silicon outer layer that feels nice on your skin. The top ball is partially silver-colored for a lovely twist. The vibrations stimulate the vagina on the inside and provide a stimulation that nobody has to know about. It\'s your secret! The vibrations are very quiet when the balls are inserted. This toy is rechargeable and waterproof, and has 10 vibration settings. These are easy to adjust using the push button. The balls also have a silicone pull cord for a safe and easy use.
