Product Highlights
- Water-activated self-lubriating sleeve technology — just add water

How to Use
Rinse the sleeve lightly with water or moisten your hands. Slide the sleeve on and enjoy the instant slickness. The self-lubriating sleeve reactivates with each wetting, so a small spray bottle or sink proximity keeps the session going. For varied stimulation, simply flip the sleeve inside out to switch between a smooth glide and a massaging ribbed texture.
Cleaning and Care
After use, wash the sleeve with warm water and mild soap. Pat dry with a lint-free cloth and let air completely before storing in the included resealable pack. Avoid silicone-based lubes, which can degrade the material. This reusable masturbator is built for many encounters with proper maintenance.
