Triple vaginal balls, also known as Kegel balls, with internal metallic spheres that rotate, stimulate, and strengthen the pelvic muscles. They consist of three balls inserted into the vagina to induce spontaneous contractions of the pelvic muscles, enhancing tone. Bi-Balls provide easy and safe training, with the triple ball being ideal for those already familiar with this practice. These Kegel balls are also an excellent ally in preventing urinary incontinence.
