• 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.

    Good to use every night...I do.
    If you suffer from dry mouth during the night, these are the perfect solution. I had tried rinses - they don't last. Sprays - they don't last. lozenges - don't last. Other tablets, only last a few hours. I can get about 8 hours relief with these. Contrary to other reviews, you do not suck on them like a lozenge...they won't last at all if you do it that way. Read the directions. They "adhere" to your back molars...don't drink or eat after putting them in...as both will either dislodge or reduce the effectiveness. However, when I don't use these, my mouth is miserable and so dry. These provide enough moisture throughout the night. The flavors aren't too bad. I've used the mint (not may favorite because I'm not a fan of mint flavor), orange and berry. I wish they had other flavors (cinnamon, licorice), but till then, I'll use these probably forever.

    Really helpful for dry mouth.
    Scent Name: Berry, Size: 100 Count
    These really work. I wear a CPAP and my mouth was so dry I was waking up with my tongue stuck to the roof of my mouth. They stick well so no worry of swallowing it during the night. I like the berry flavor.
