Meet SEI MIO Silent Authority

Some toys whisper. This one makes a statement. SEI MIO Silent Authority is a progressive, interchangeable ball gag set designed for those moments when giving up words makes everything else feel louder. Comfortable, adjustable, and made with body-safe materials, it lets you dial the intensity up or down without needing a whole drawer of different gags.

Want a gentle “getting used to it” fit? Easy. Ready for a fuller, more surrender-forward feel? Swap and go.

What makes SEI MIO Silent Authority special?

Three sizes. One strap. Endless options.

This set includes three quick-swap silicone balls so you can choose the vibe that matches your mood, your comfort level, and the kind of control you’re playing with.

• Progressive ball sizes: 4 cm, 4 cm, and 5 cm for a smooth step-up in “mouth-filling” intensity
• Quick-swap design: change sizes without fuss when you want to escalate or ease off
• Body-safe build: medical-grade silicone balls, nickel-free metal fittings, and a PU-leather strap
• Comfort-first strap: padded and adjustable up to 61 cm for a secure fit that doesn’t feel punishing
• Quick-release velcro closure: simple to remove when play ends or when you need it off fast

Benefits of SEI MIO Silent Authority

It’s a choose-your-own-intensity set. Instead of committing to one size forever, you can explore what feels best right now, from a lighter introduction to a more commanding, “no talking, just feeling” experience.

It supports confident play. The adjustable, padded strap helps you find a snug, stable fit, while the quick-release closure adds peace of mind. That combo makes it easier to relax into the moment, which is kind of the whole point.

It looks as good as it feels. Clean lines, a bold aesthetic, and that unmistakable gag silhouette turn power exchange into something you can see as well as feel.

Why choose this set instead of a single gag?

Because your comfort and your cravings aren’t fixed settings. Silent Authority is built for progression: start smaller, get familiar, then size up when you want more presence, more drool-worthy surrender, and more delicious frustration.

It also saves you from buying multiple gags just to find your sweet spot. One strap, three options, and the freedom to switch things up whenever the mood shifts.

How to use SEI MIO Silent Authority

1. Pick your size and attach the ball to the strap using the quick-swap system.
2. Adjust the strap for a secure, comfortable fit. Snug is good. Painful is not the goal.
3. Set a non-verbal safe signal before you begin, since clear speech won’t be an option.
4. Start with short sessions and check in often, especially when trying a new size.
5. Switch sizes as desired to build intensity or ease back down.

Before You Play: Fit, Comfort & Communication

Silent Authority is all about confidence and control—so set yourself up for a smooth experience. Start with the smallest silicone ball (Ø 4 cm), then work up to Ø 4 cm and Ø 5 cm as comfort grows. Adjust the padded PU-leather strap so it’s snug, not crushing.

Because speech won’t be clear, agree on a non-verbal stop signal first (drop an item, hand tap, finger snap—whatever you can do easily). And keep the wearer supervised the whole time.

• Don’t use if the wearer can’t breathe freely through their nose (colds, allergies, congestion).
• Avoid if you’re dealing with nausea, reflux, or jaw/TMJ pain.

How Long to Wear It

Think “tease,” not “marathon.” For first timers, aim for 10–15 minutes, then take a break. Many people prefer keeping sessions under 20 minutes to avoid jaw fatigue. If it hurts, it’s not a challenge—it’s a cue to stop and reset.

Cleaning & Hygiene (Silicone Balls + Strap)

Silicone balls (medical-grade, non-porous)

After use, wash with warm water and mild soap, then rinse well and dry completely.

• For a deeper clean, you can boil the silicone balls only for about 3 minutes.
• A toy cleaner is optional; skip harsh chemicals.

PU-leather strap + nickel-free metal fittings

Wipe the strap with a damp cloth and a little mild soap, then pat dry. Wipe metal parts clean and dry them well to help prevent corrosion.

• Do not boil, soak, or fully submerge the strap.
• Let everything dry fully before storing (padding needs extra time).

Storage & Ongoing Care

Store in a clean, dry pouch or container away from heat and direct sunlight. Before each use, check for cracks, tears, sticky patches, or loose fittings. If anything looks damaged, retire it—your safety is the whole point.
