• DESCRIPTION

From the moment I first wore the flat-style ABS chastity cage, I knew this wasn’t just another toy on the shelf—it was built for people like us. People who crave discipline, subtlety, and the kind of sensory detail only a well-thought-out design can deliver.

Let’s talk comfort first. The cage is made of durable, non-toxic ABS resin, but don’t let the word “resin” fool you. This thing feels smooth—silky smooth. No rough seams, no harsh edges. Just soft, rounded curves that hug your body like it belongs there. Whether you're new to chastity or a seasoned locked boy, you'll appreciate how this cage feels almost invisible against the skin. No pinching, no rubbing—just a quiet, constant presence.

The colors? Honestly, they’re a sweet surprise. Four vibrant options, like pieces of candy, each with its own playful vibe. I went with the soft pink at first—cute, but not silly. Just the right amount of sweetness without taking away from the seriousness of the lock.

It comes with four different base ring sizes, which made it easy to find the perfect balance between security and wearability. I switch them depending on the day—some days I want tight, unforgiving control. Other days, I’m in the mood for a little breathing room. The flexibility is everything.

Additionally, the F3216B comes with five One-Time Plastic Locks, providing a travel-friendly solution that avoids the complications of metal cages at security checkpoints. These locks allow for a smooth passage through airports, train stations, or other public spaces without triggering alarms, offering privacy and peace of mind. As someone who travels a lot, this tiny detail means the world.

Now, the flat design is genius. No awkward bulges, no visible outlines under clothing. I’ve worn it on the subway, at the gym, during flights—zero stares, zero embarrassment. It stays close to the body, tucks perfectly, and even during long wear, it doesn't shift or become uncomfortable.

And then there’s the catheter. This is where things get really interesting. The F3216B features a unique inverted steel ball catheter that does more than just provide stimulation—it offers true dual-purpose functionality. The stainless steel bead gently presses inward, enhancing the feeling of containment and deep submission. But what truly impressed me was how clean and practical it is. You can urinate through it easily—no spraying, no discomfort, no mess. It keeps everything neat and controlled, even during long-term wear. And if you ever want to dial things back and go with a more classic setup? Just remove the inverted steel ball catheter, and the F3216B transforms into a traditional flat cage. That level of modularity really makes it stand out.

Cleaning is easy, too. The materials don’t absorb odor or bacteria, and the whole piece rinses clean in seconds. I’ve worn it for days at a time, and it still feels fresh every morning. No irritation, no signs of wear. Just that same reliable shell keeping me exactly where I belong.

This isn’t just a chastity cage. It’s a lifestyle upgrade. Flat, discreet, colorful, and intensely intimate. Every detail—from the inverted steel ball to the smooth finish—is built for pleasure through denial. And as someone who’s lived locked, I can tell you: this cage gets it.

    Not Boerboel proof
    I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately. She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole. It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.

    Favorite Toy
    Size: Medium/Large, Product Packaging: Standard Packaging
    My dog is a 3.5 yr old mix and this toy has been her favorite toy by far for three years. She likes it as a squeak toy, loves it as a tug toy and can't live without it as fetch toy. I roll it on its edge outside and she chases it - sometimes it take cool bounces or swerves and sometimes its just rolls straight and fast and whatever it does she can't get enough of it. She demands we play fetch with it at least three times a day. She's not a great releaser of fetch toys so there's plenty of tugging play involved too. We've had three of these over three years, but she's 75 pounds of muscle and it gets a work out every day so it's a really tough toy. All dogs are different, so I don't know what your dog will think, but it's been a fantastic toy for our girl.

    So Bad
    Size: Medium/Large, Product Packaging: Standard Packaging, Size: Medium/Large, Product Packaging: Standard Packaging
    Had high hopes for this toy as Kong is fantastic with aggressive chewers as or Lulu is. This toy didn't last 30 minutes before she was able to tear it apart. The rubber and plastic are not of the same quality on nearly all there other toys she has. Have found better toys for half the cost. Kong needs to do better.

    Very cute, good quality
    Style: Lambchop, Size: 10", Style: Lambchop, Size: 10"
    Our Two year-old Great Pyrenees rescue loves her Lambchop. She’s fairly gentle with it, but it did accidentally rip so we had replace it since she loves it so much. No fault of the product. The product is very well made, She just got a little rough with it.
