Two hands, one distance
The hands are fixed in relation to each other the moment the cuffs close. No joint, no play — the distance stays exactly as it is.
The spikes on the inside work from the first second, from every direction. Every movement answers back.
And when the cuffs eventually come off, the marks are the proof.
- Rigid connection — the hands can neither be turned nor pulled apart
- Spikes on the inside — every movement is felt
- For wrists and ankles — the larger sizes are made for ankles
- Central mount for rope or chain, chain link lockable
- Also available without spikes
- Closure: recessed steel bolt, held in place by magnets
- Hex key included
- Designed and manufactured in Germany
ThornReign Cuffs or Double Cuffs?
The Cuffs lock separately and can be fixed independently — you decide, session by session, how much movement stays possible. With the Double Cuffs, that decision is already made: the hands can neither be turned nor pulled apart. Rope or chain can be added via the central mount.
Pairs well with our Anchor Mitts — the cuffs take the movement, the mitts take the hands.
Before first use: please read the safety notes.
Which size fits me?
The size figures stand for wrist width × wrist height, in centimetres. A cuff marked "6.5 x 5.0 cm" therefore fits a wrist 6.5 cm wide and 5.0 cm high.
How to measure
Width: directly behind the wrist bone, straight across the wrist.
Height: at the same point, perpendicular to the width measuring line.
Measure snugly, but without pressing into the skin. A simple ruler is enough.
Which size to choose
If your value matches exactly, take that size — otherwise the next size up. Sizes rise in 5 mm steps, so you'll never be far off.
Never choose smaller. One size up is uncritical: the cuffs sit more loosely, but you will not slip out — and the spikes still work, because they act on the skin as you move. Only two sizes up becomes too wide.
Not sure? Write to us. We'll help you find the right size before you order.
Full description
Unlike conventional restraints, the effect doesn't begin with the fixing. The spikes on the inside press their marks into the skin and create a slight, deliberately unpleasant pain — from the moment they go on.
The central mount. A rope or chain can be attached through the recess between the two cuffs. A chain link can be locked in place with the central screw — the screw sinks fully into the material, so it can no longer be undone without a hex key. That turns the handcuffs into a fixed anchor point for whatever comes next.
The closure. A steel bolt is recessed into the cuff and held in position by magnets. The enclosed hex key opens it — quickly, reliably and without force. The cuffs come off as fast as they go on.
If you'd rather do without the spikes, choose the version without.
Safe use
ThornReign Double Cuffs are BDSM tools for conscious, consensual sessions. Improper use may result in injury.
- Do not use on injured skin or numb areas
- Check blood circulation regularly
- Never wear unattended for extended periods
- Keep the hex key within reach
- Remove immediately in case of pain beyond the desired level, numbness or discolouration
- Check for damage and closure function before each use
- Do not use under the influence of alcohol, drugs or medication
Always ensure clear communication, safe signals and attention to your play partner's physical condition. BDSM requires responsibility — use this toy with caution, respect and mutual consent.
