LUNA beads are for women who treasure their sensuality - a combined pleasure and fitness system that enables women and their partners to enhance their sensations for years to come. Developed as a stylish and discreet alternative to the traditional 'geisha balls', LUNA beads work to strengthen the vaginal wall and PC muscles through more effective Kegel exercising. This makes you more responsive to touch, improving muscular control and allowing for the most intense and stimulating orgasms in the future. When placed delicately inside, they deliver a subtle, movement-induced vibe for a more comfortable workout, revealing the pleasures that caring for your body will bring.
