Common Questions

How do I clean this stroker?

To clean the MasterJack, use warm water and a mild, toy-safe soap. Gently wash the interior of both holes and the exterior, then rinse thoroughly. Pat dry with a lint-free cloth or allow it to air dry completely before storing.

Can I use this with different types of lube?

Yes, the Plus+SILICONE material is compatible with water-based lubricants. Avoid silicone-based lubes, as they can degrade the silicone material over time and damage the toy.

What makes the two holes different?

One end features a tighter, ribbed and nubbly interior designed to add intense friction and sensation to your shaft. The other end is a larger, ringed opening for a smoother, more gliding sensation during use.
