The new Sphere Intimate massager from Joya features two totally separate yin-yang shaped massagers presented in one sleek, acrylic storage case. Each massager offers 5 surprisingly strong, discreetly quiet modes. The white half offers 5 graduating speeds, while the black half offers 5 unique pulsation modes. Made from premium-grade, non-porous, non-toxic and hypoallergenic ABS plastic, Sphere's shell is waterproof and easy to clean, and boasts a silky PU coating which gives their surface a sensual feel that's easy to hang on to. The tear-drop shape of each massager can easily reach around the body's curves. Waterproof. Each massager measures 4.85" x 2.5' x 1.4". Each massager requires 2 AAA (total of 4) batteries (not included).
