Vesper is a vibrator that can be worn like a pendant on a necklace. The multi-speed vibrator, contained in a solid slim device, can be adjusted manually to varying speeds and charged via USB. The pendant and matching chain are both made from highly polished 316 stainless steel, but are separable, allowing the user to decide whether to use as jewellery or as a vibrator. The device is water-resistant and available in three colours.
