Love Stone Yoni Eggs are tools used to perform exercises to strengthen your pelvic muscles. In addition to that, they help you access your sexual power and awaken your sensuality through awareness of your yoni (sacred space). If you have mild incontinence issues, you can practice with a yoni egg daily to strengthen and tone your pelvic floor. This set of three eggs includes a Small, Medium and Large egg: * Small size: 30mm x 20mm * Medium size: 40mm x 25mm * Large size: 45mm x 30mm Work your way up from the large egg to the small. The small is for advanced users and over time you will be able to work towards gripping the smaller egg as your pelvic muscles strengthen.
