Get Ready to Master Your Pleasure with MASTERJACK! 💪🍆

Hey pro-level gooners and hardcore strokers! If you crave something thick, heavy, and packed with pleasure, the MASTERJACK is here to elevate your JO game. This isn’t your average stroker—it’s a hefty, fleshy beast designed for those who love to go hard and deep. Get ready to experience the ultimate in solo satisfaction!

Key Features:

  • Dual-Function Pleasure: Two holes to explore—one with a tight, ribbed butt-pucker and the other with a ringed, gaping hole for a smoother ride.
  • Ergonomic Handle: Built-in handle with industrial diamond plate grips ensures a firm hold, no matter how wet and wild things get.
  • Extra-Soft Plus+SILICONE: Made from our softest silicone blend for a fleshy, warm feel with a suede-like finish.
  • Durable and Body-Safe: Non-toxic, phthalate-free, and designed for intense, prolonged use.

Unleash the Beast

Imagine this: you're deep into a marathon session, and you need something that can keep up with your relentless pace. MASTERJACK is your perfect partner. Its hefty build and fleshy feel make every stroke an intense experience, while the ergonomic handle ensures it stays in your grip no matter how greasy and sloppy things get.

With two distinct holes to choose from, you can customize your pleasure. The tight, ribbed butt-pucker offers intense stimulation, while the ringed, gaping hole provides a smoother, sloppier ride. Flip it over and switch up the sensation whenever you want—it's all about what feels best for you.

Lube Up and Go Hard

LUBE SAFE: Use with water-based or silicone-based lubricants for an ultra-slick experience.

Easy Care for Long-Lasting Fun

CARE: After your session, wash the MASTERJACK in warm, soapy water and let it air dry. Store it separately in a breathable cloth pouch or cotton sock to keep it in prime condition for your next goon-fest.

  • Length: 5.5 in / 14 cm
  • Width: 3 in / 8 cm
  • Depth: 2 in / 5 cm
  • Circumference: 7 in / 18 cm
  • Inside Diameter: 1-2.5 in / 3-6 cm

How to Use MASTERJACK

1. Getting Started:

  • Unpack and Inspect: Remove your MASTERJACK from its packaging and give it a quick inspection. Make sure it’s clean and ready for action.
  • Choose Your Lube: Apply a generous amount of water-based or silicone-based lube to both yourself and the stroker. This ensures a smooth and enjoyable experience.

2. Using MASTERJACK:

  • Select Your Hole: Decide which end you want to start with—the tight, ribbed butt-pucker for intense stimulation, or the ringed, gaping hole for a smoother, sloppier ride.
  • Insert and Enjoy: Slowly insert yourself into the chosen hole. Use the ergonomic handle to maintain a firm grip and control the stroker’s movement.
  • Adjust Your Grip: Squeeze the stroker and experiment with different angles and pressures to find what feels best. The ergonomic handle with diamond plate grips makes it easy to keep a solid hold, even when things get slippery.

3. Switching It Up:

  • Flip and Repeat: Want to change things up? Simply flip the stroker and slide into the other hole for a different sensation. The dual-function design lets you easily switch between the two textures for varied pleasure.

4. Two Guys, Double the Fun:

  • Share the Experience: MASTERJACK is designed to be enjoyed solo or with a partner. Two guys can use either end at the same time for an incredibly intimate and thrilling experience.
  • Get in Position: Align yourselves so that each of you has access to one end of the stroker. Lube up generously and insert into your respective ends.
  • Synchronize Your Movements: Communicate and find a rhythm that works for both of you. The shared sensation and mutual pleasure will take your connection to the next level.

5. Aftercare:

  • Clean Your Stroker: Once you’re done, wash your MASTERJACK thoroughly with warm, soapy water or your favorite sex toy cleaner. Ensure all lube and bodily fluids are removed.
  • Dry and Store: Pat dry with a clean towel and allow it to air dry completely. Store the stroker separately in a breathable cloth pouch or cotton sock to keep it in prime condition.

So, what are you waiting for? Grab your MASTERJACK and get ready to master your pleasure. It's time to go hard, go deep, and goon like never before! 💪🍆

Love these floating shelves!

These shelves are perfect for my kitchen! They were easy to install. All the hardware was included. They are durable and sturdy and gave my kitchen wall an instant face lift!

Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
