Signet Ring is intended both as a partner vibrator and for use by men on their own. The rechargeable, waterproof sex toy produces 10 superimposable vibration programmes, which can be expanded with additional settings via an app. Outwardly, the vibrator is notable for its organic shape and matt black colour. The smooth silicone material flexibly adjusts to the penis size and, furthermore, prolongs sensual pleasure through a blood congestion effect.
