What Is the ArcDuo™ Prostate Massager?

The Romulus ArcDuo™ is an app-controlled dual-motor prostate massager designed for internal prostate and external perineal stimulation.

Its curved internal section is shaped to direct stimulation toward the prostate area, commonly referred to as the P-spot, while the external arm rests against the perineum to provide a second point of vibration.

Unlike a traditional butt plug that primarily focuses on anal fullness, ArcDuo™ is designed around targeted prostate stimulation. Its dual-motor system adds vibration both internally and externally for a more layered experience.

ArcDuo™ also supports long-distance app control, allowing you to control the experience through a compatible smartphone or share control with a partner from another location.

With 9 vibration modes, dual-zone stimulation, smartphone control, waterproof construction, and USB charging, ArcDuo™ brings targeted prostate massage and connected partner play together in one streamlined toy.
