Onyx Bunny collection
Restraints
Restraint can make attention feel deliberate without making a night complicated. This collection covers cuffs, collars, bed and spreader kits, chastity items and gags. It suits adults who want to explore holding, anticipation and shared control, and who agree on boundaries before anything is fastened.
Check the dimensions against the wrists, ankles or waist where an item will sit. A cuff should leave room for two fingers and must never cause numbness, tingling, coldness or a change of colour. Keep keys, releases and safety scissors within reach, never put pressure on the neck, and never leave a restrained partner alone. Each product page carries the warnings for its type, and the beginners guide covers signals and aftercare.
Every order ships to the European Union, Canada or the United States in a plain outer box with no product names or Onyx Bunny branding, and the card statement shows a neutral descriptor. No VAT is charged at checkout; EU buyers pay import VAT and a carrier handling fee on delivery, as the shipping page explains.
Selected from this collection
Metal Tassel Flogger
A metal-tassel flogger with chain tails and decorative gems. It is heavier than a leather flogger, so it gives a thuddier sensation and is best used gently.
CBT Ball & Wrist Stock
A rigid stock with two outer holes for the wrists and a smaller centre hole for the testicles. Made for CBT (cock-and-ball torture) and ball-restraint play between experienced partners.
Wooden Shackles
Solid wooden shackles that hold the wrists and neck together, in the style of a pillory. A heavier restraint for couples exploring power play.
Wrist & Ankle Shackle Bars
Heavy-duty shackle bars that hold the wrists and ankles in place. Built for longer restraint scenes where the position stays fixed.
Locking Handcuff Shackle
A locking handcuff shackle that joins the wrists with a lockable closure. A secure step up from simple cuffs.
Handcuff Kit
A bondage kit that joins wrist cuffs to a neck collar. It keeps the hands held close to the body for restraint play.
Leg Splitter Rack
A spreader rack that holds the hands, feet and neck in an open position. A large restraint piece for experienced couples.
Questions about restraints
How tight should cuffs be?
Snug but never tight: two fingers should slide underneath. Release at once if hands or feet go cold, tingle, go numb or change colour.
What do we need before trying restraints?
An agreed safe word or signal, the key or release within reach, safety scissors nearby, and a plan never to leave the restrained partner alone.
Are restraints suitable for beginners?
Yes. Start with soft cuffs or a strap set, keep sessions short, and talk about limits before anything is fastened.
