Best For:
- Experienced stroker enthusiasts
- Dual-texture exploration
- Firm-grip control during solo sessions
- Textured internal sensations
- Heavy, substantial handheld toys
The MASTERJACK by Oxballs is a dual-entry stroker built for hands-on control. Moulded from their softest Plus+SILICONE blend, it has a suede-finish exterior with raised diamond-plate grips along the handle and body — designed to stay secure even when lubricated. At 8 ounces, it's heavier than most entry-level strokers, giving you a substantial, flesh-like feel that responds to pressure.
Two textured tunnels offer distinct experiences: one end features a tighter entry with internal ribs and nubs that grip along the shaft, while the reverse side opens to a wider, ringed canal for smoother glide and less restriction. The inner shaft extends 5 inches, accommodating most sizes with room to adjust depth. The integrated handle loop ensures you maintain grip throughout extended sessions, and the blunt exterior edges rest comfortably against your palm.
This isn't a beginner's first stroker — the heft and dual textures are calibrated for users who know what sensation they're chasing and want manual control over speed, angle, and pressure without the toy slipping mid-stroke.

How to Use
Apply water-based or silicone lubricant to your shaft and the interior tunnel opening. Insert through either end depending on desired tightness — the ribbed side offers more resistance, the ringed side allows smoother movement. Grip the handle loop or diamond-plate body to control stroke depth and speed. After use, rinse the interior thoroughly with warm water and mild soap, then air-dry completely before storing in a breathable pouch.
