Suspension bondage often needs a slightly different kit to other bondage types, not least because of the extra safety concerns. Suspension cuffs need to be sturdier and more load-bearing than other bondage cuffs often are, not to mention they need reinforced d-rings! They may also be padded or covered at the edges, and they're usually wider than other cuffs - all to make sure that the wearer is in a safe, sustainable position that they can keep up without damaging themselves. It's vital not to perform suspension bondage with cuffs that aren't designed for it, so make sure you make the extra investment if you'd like to play around with being strung up!
Collaring is a common practice in the BDSM community. People in all kinds of Dom/sub relationships often like to have something physical to symbolise the bond between them, be that a Daddy and his little girl or a Dominatrix and her slaveboy -and the giving and wearing of collars is frequently used in this way. For many people, a collar is a clear sign of a deep commitment and has a sincere emotional meaning for them. Of course, the objects used in this way aren't always literally collars--some kinky couples like to symbolise their ownership using bracelets, anklets, rings, chains or any other adornment that has a particular meaning for them.
Bondage cuffs are great especially if your priority is speed over finesse! They can be used to tie someone's wrists or ankles together easily, either separately or into a hogtie. They're excellent for tying someone spread eagle to a bed or a piece of bondage equipment, and they make it easier than ever to lead your partner around. If you're interested in bondage, it's well worth investing in a good set of wrist and ankle cuffs - costlier ones are more durable and comfortable, too, making them a great choice for longer scenes and sessions. If you pick ones you especially like, they're also a great addition to your fetish clubbing outfits!
