    SMARTBALLS UNO – Have a Ball

    Kegels for all!

    • Materials: silicone and non-porous elastomed
    • Size: 1.4 in
    • Wear for up to 30 minutes at a time
    • Designed and handcrafted in Germany

    SMARTBALL UNO - Also available as a kit

    Can't decide between the SMARTBALL UNO and an awesome vibrator? You don't have to. Our TRUE LOVE KIT combines the SMARTBALL UNO and our bestselling AMORINO vibrator, while the LITTLE BLACK KIT pairs it with the powerful MISS BI - BLACK LINE dual motor toy. Both kits come with TOYFLUID lube, our spray CLEANER, an adorable antimicrobial Karim Rashid TOYBAG, and a TOYBOX to store your new favorite toys. 

    With a total value of $216.95, the TRUE LOVE KIT retails at only $134.99, while the LITTLE BLACK KIT is marked down from $266.95 to $179.99.

    We cut the classic SMARTBALLS design in half, making a Kegel weight that beginners, folks with a tilted uterus, and anyone who’s had a hysterectomy can use comfortably. Just hold the SMARTBALL inside and go about your business, or do your usual squeeze-and-release Kegel exercises around it for a more intense workout. The weighted ball inside will bump and roll as you move, making your muscles work even harder and bringing stronger orgasms into your life that much faster.

    SMARTBALLS have an internal device designed to trigger involuntary pelvic floor contractions once inserted into the vagina. 


    The "EASY IN"-finger mould allows for easy insertion of the SMARTBALLS


    The stable retrieval band is barely felt while bearing and makes removing the SMARTBALLS particularly easy. 


    Pelvic muscles act like a sling, extending from the pubic bone to the tail bone. By wearing SMARTBALLS they are trained without effort. 


    SMARTBALL UNO are ideal for women who want to start their training with small weights. 


    It’s submersible waterproof!


    All FUN FACTORY toys are invented, developed, designed AND produced in Bremen, Germany.


    FUN FACTORY offers a diverse and colorful spectrum of toys all made with 100% medical-grade silicone!


    Carefully clean the toy before first use and after each use with warm water and a mild soap. The CLEANER is especially suited for cleaning erotic toys as well as for gently washing genital areas.

    WARNING: The use of silicone-based lubricants, oils, and creams (suntan lotion or sunscreen, lip care products, essential oils, coconut oil, and edible oils of all types) can cause irreversible damage to the control unit and the entire toy.
