Sex Extra 70mm Metal Cuffs by NANMA Corporation

Sex Extra 70mm Metal Cuffs by NANMA Corporation are high-quality metal restraints that lock securely around wrists or ankles with a twist-key mechanism.

Design and build

Sex Extra 70mm Metal Cuffs by NANMA Corporation are precision-engineered restraints built from solid metal with a polished silver finish. The 70mm diameter accommodates various body sizes, making them equally effective as wrist or ankle restraints. The twist-key locking mechanism creates that definitive click which signals the psychological shift into control, while the substantial weight provides constant awareness of restraint throughout your session. Unlike novelty cuffs, these deliver genuine security without compromising comfort during extended wear. The cool metal surface heightens skin sensitivity, adding an extra sensory layer to bondage play. Metal restraints sit firmer against the skin than many cuff restraints made from softer materials, which is why they suit scenes where the weight and psychological impact of control matter most.

The quick-release function means safety is never compromised. Your partner can free you instantly if needed, building confidence to explore more intense dynamics without anxiety. The polished finish catches light with every movement, improving the visual impact of restraint during scenes.

Negotiating, using it and winding down

Before play begins, discuss boundaries clearly with your partner. Establish a safeword so you can stop immediately if needed. Check that the 70mm diameter fits comfortably around your wrists or ankles without cutting off circulation—there should be room for one finger between the cuff and your skin. Have the twist keys within easy reach of the top before locking, ensuring quick-release access at any moment. Start with shorter wear periods to build trust and familiarity with the sensation of metal restraint and weight.

During your scene, focus on the psychological shift the definitive click creates. The cool metal heightens skin awareness while the weight reinforces your restrained state. When the scene ends, remove the cuffs promptly and check your skin for any marks or irritation. Aftercare is essential—spend time reconnecting with your partner, reviewing what worked, and discussing what to adjust next time. Many people find that bondage collars complement wrist cuffs well by extending the sense of control throughout your body during a scene.

Who should buy it

Care and storage

After each use, wipe the cuffs clean with a soft, dry cloth to remove any moisture or residue. Inspect the locking mechanism regularly to ensure it operates smoothly—a small amount of silicone-based lubricant on the twist mechanism keeps it responsive. Store the cuffs in a cool, dry location away from humidity, which can cause discolouration or corrosion. Keep the twist keys with the cuffs so they are never misplaced. Avoid dropping or striking the cuffs, as impact can damage the locking mechanism or dent the metal.

What to expect

The first time you lock these cuffs, the weight and cool metal will feel immediately different from lighter restraints. Many people are surprised by how much that authentic metal sensation deepens their psychological experience of restraint. The definitive click of the twist-key mechanism creates a profound moment of transition—it is not subtle, and that is entirely the point. Expect heightened skin awareness as the cool metal sits against your wrists or ankles, and plan for a brief adjustment period as your body settles into the sensation.

The 70mm diameter fits most people comfortably, but verify the fit before your first scene. There should always be room for one finger between the cuff and your skin; never force them on or leave them locked if circulation feels compromised. The cuffs themselves require minimal maintenance—a simple wipe with a soft cloth after use keeps them clean and prevents discolouration from moisture or sweat.

These restraints hold up well to regular use when treated with care. The solid metal construction does not degrade, and the twist-key mechanism remains responsive if kept clean and lightly lubricated. People tend to get on well with them if they benefit security and psychological impact; those who prefer soft, padded restraints or adjustable sizing often find these too rigid by comparison.
