About this material — Silicone

Silicone is a smooth, flexible polymer (a polysiloxane). It’s non-porous, so it doesn’t absorb fluids and wipes clean easily, and it warms to body temperature.

Care. Wash with mild soap and water or a toy cleaner. Pair with a water-based lube — silicone lube can affect silicone over time.

Oxballs MasterJack Double Penetration Stroker Jo Black Ice

The MasterJack Double Penetration Stroker is a heavy, fleshy beast designed specifically for pro-level gooners who demand something thick, substantial, and versatile. If you find standard strokers a bit too flimsy for your sessions, Oxballs has engineered a solution that feels blubbery and substantial in your fist. This isn’t a delicate toy; it is a rugged, dual-entry instrument built for those who want to fuck hard and explore different sensations without switching gear. The Black Ice edition brings a sleek, dark aesthetic to a design that is as much about tactile weight as it is about internal texture.

Key Features

  • Dual-entry design featuring two distinct holes: a tighter, ribbed butt-pucker for intense friction and a larger, ringed, gaping hole for a smoother, sloppier sensation.
  • Crafted from Oxballs’ exclusive Plus+SILICONE blend, providing an extra-soft, fleshy, and warm feel.
  • Industrial-grade diamond plate grip surface ensures you maintain control during intense use.
  • Integrated handle grip designed to stay secure in your hand, no matter how much lube you use.
  • Non-toxic and phthalate-free material composition for peace of mind during solo play.
  • Substantial dimensions: 5.5in (14cm) in length with a 7in (18cm) circumference.
  • Versatile internal diameter ranging from 1in to 2.5in (3-6cm) depending on the entry point used.

Achieving the perfect session with the MasterJack requires the right amount of lubrication to complement its unique texture. Because this toy is made from a premium silicone blend, you have flexibility in your choice of lubricant. You can use water-based lubes for easy cleanup or silicone-based lubes for a longer-lasting, slicker glide. Just remember that when using silicone-based lubricants, you should avoid using them with silicone-based condoms or other silicone toys to prevent material degradation, though this heavy-duty stroker is built to handle the friction of your favorite heavy-duty lubes. For the smoothest experience in the larger, ringed hole, don’t be afraid to get generous with the application to let that “sloppy” sensation truly shine.

Maintaining your MasterJack is straightforward but essential for longevity. After every session, wash the toy thoroughly in warm, soapy water to remove all traces of lubricant and bodily fluids. Once cleaned, allow it to air dry completely before storage. To protect the delicate diamond plate grips and the soft Plus+SILICONE surface, we recommend storing your toys separately. Using a breathable cloth pouch or even a clean cotton sock will prevent the material from picking up lint or reacting with other accessories. By following these simple care steps, you ensure that the MasterJack remains a centerpiece of your collection for a long time to come.

Elevate your solo play sessions with the unmatched weight and versatility of the MasterJack. Explore the full range of heavy-duty pleasure at Phareros.com.

Brand

Oxballs

Oxballs is Stephen Lane's brand, part of Blue Ox Designs, making men's gear — cockrings, ball stretchers, sheaths and plugs — for the leather and fetish market since around 2008. They cut their own moulds instead of buying stock ones, which is why the shapes don't look like anyone else's.

Worth knowing before you buy: the silicone pieces are platinum-cure, which is the good stuff — non-porous and fully sterilisable. But the range also includes TPR and silicone/TPR blends, which are porous and can't be. The material is listed per item, and it's worth checking, because the two sit side by side at similar prices.
