Getting in shape is most fun when you can measure the results, which is why this sensual set contains 3 different love balls: All three have a diameter of 1.34" and are thus the same size, but each has a different weight. Start with the lightest and gradually work your way up. In this set, the lightest ball weighs 2.11 oz (normal), the middle one 2.66 oz (experienced) and the heaviest 3.23 oz (advanced). Just a few minutes of training every day will enable you to take your love life into your own hands! Wearing the love beads for about 15 minutes a day trains your pelvic floor muscles - the muscles that enable you to experience breathtaking orgasms. This training not only benefits you, but also your partner: if you train your pelvic floor muscles, your partner will experience the ultimate sensation of tightness.
