Our usage tips
How to use the TRIUNE Metal Hard 12.5 cm BDSM restraint collar
- Agree on a safe word or a stop signal before you start. With something around your neck, a gesture is better because it does not rely on being able to speak.
- Open the side hinges outwards and place the collar around your neck.
- Close it and check that it is not too tight. You must be able to breathe and swallow normally while wearing it.
- Fit the padlock through the hole at the back if you want to keep the collar locked shut. Keep the keys within reach.
- Attach the leash or anchor attachment to the front ring.
Cleaning
Wipe it with a cloth dampened with water and a little mild soap. Dry it thoroughly, including the hinges, and store it dry with the padlock and keys.
Our advice
- Always keep the padlock keys within reach so you can unlock it straight away.
- Do not pull hard on the leash. If you secure the collar to an anchor point, leave enough slack to keep any jerking force or weight off your neck.
- Do not use it to put pressure on your neck or restrict your breathing.
- Do not leave anyone alone while they are wearing it, especially with the padlock locked.
- Do not sleep with it on.
- Remove it straight away if you feel dizzy, have difficulty breathing, feel pain or notice marks on your skin.
