Since they're for soft bdsm they're probably easy to break, especially for a grown man
Usually when you find "fur cuffs" they are made of plastic or very pliable metal. People into soft BDSM - the BD, bondage and discipline, side of BDSM - are not trying to restrain their partner beyond the limit of their strength or injure them in any way. The restraints are just for effect. The person remains still or complies because they choose to, not because they actually can't get free or move. Things like silk, satin and fur or feathers are used to tease rather than riding crops, paddles and biting chains. Those are used in the SM side of BDSM. Most items found at the average novelty store or sex shop are for soft BDSM. Hard BDSM toys are either special ordered or found at a hardware, sporting goods or equestrian store and some toys you have to build yourself.
