Mismatch or not, Vita has a colorful appearance and is a great help for a stronger pelvic floor! Strong pelvic floor muscles can contribute to experiencing a more intense orgasm and also help combat involuntary urine loss after, for example, pregnancy. Alternate training for about 20 minutes a day with the different weights. Start with the single holder and the purple, yellow or turquoise ball; these weigh 40 grams each and are a perfect start. Use a small amount of water-based lubricant for a comfortable feeling. Over time, you can move on to the double holder and combine the pink and blue ball; these weigh 50 and 60 grams. Both holders are very flexible and stretchy so it's easy to change the different balls. There's a convenient cord at the bottom. This set is made of body-safe silicone material. You can easily clean this with lukewarm water and a mild antibacterial soap or a toy cleaner.Measurements: The single holder has a total length of 10 cm (3.94 in.).
