With its curved shape, the F3 nestles perfectly to the shape of the female body. The tender curves with silky smooth, body-friendly surface are colourfully and haptically accentuated by contrasting elements made from soft silicone. The embedded controls are integrated into the feminine shape and can be easily and intuitively accessed during use. The battery compartment is securely locked and can be easily unlocked with the puristic, enclosed opener – if this is not available, a coin can also be used. The firm body enables the perfect transmission of vibrations.
