Smartballs Uno & Duo Fun Factory

19.9024.90 IVA incluido

Fun facts: 1) The muscles in your pelvic floor contract when you orgasm. 2) A stronger pelvic floor can mean bigger orgasms. 3) Using those muscles to hold a weighted ball inside your vagina strengthens them. Lube up these smooth, silicone balls, insert them, and use your muscles to hold them inside your vagina. From there, you can do squeeze-and-release exercises or just go about your life! Each ball contains a small, round weight that bounces and rolls as you move, making your muscles work harder to keep the SMARTBALLS in without you having to make a conscious effort. It’s also really fun to wear during a spanking.

They can help prevent incontinence, boost blood flow to help you fight off infections, get your body ready for childbirth, and assist in healing after childbirth. If you want to give a partner a squeeze during sex, strengthening your pelvic floor also helps with muscle control.

SMARTBALL UNO are for people with a shorter vaginal canal and the DUO is two-ball design engages more of your muscles.. If you’re not sure, there’s no harm in starting with the SMARTBALL UNO!
