The design is very generic and nothing about the cuffs stands out. They are plain, metal hand cuffs. The cuffs are, however, very strong. It is not something you want to be wiggling around in too much because they can really bite your wrists. The metal is solid but light, and can be very, very cold. They are smooth and didn't have a strong smell to them, but if you really sniff them you will smell the metal! LOL I do have bigger wrists, but in the end you can make them work. For the average person, they are a good fit. Like I said before, they are like the generic cuffs you can get at the dollar store; they even have the little lever on the side as a safety, but overall, they are much stronger.
It worked very well for me. The role-playing was amazing; after we practiced with the cuffs a little, it ended up being super fun. When I first opened the box and saw these cuffs in a plastic bag I thought, "What the hell is this?!" But, after playing with them and testing them out, they ended up being a load of fun! The second my husband saw them he told me he had loads of things planned, and has pretty much secured me everywhere in the house.
I don't want to get the cuffs wet because of them being made out of metal, water is out of the question. We haven't really gotten down and dirty with them, and I just dust them off when I don't have anything to do. They are very easy to care for. They can pretty much go anywhere because they are thin and light. I keep them in a small silk baggie in my drawer, but when left out it looks like something the kids were playing with.
Really, the cuffs were packed very bulky. They come in a small plastic pouch/bag that is thrown in to this box that you could fit 10 pairs of cuffs in. There are no instructions to the cuffs because, come on, if you don't know how they work then you need to come out of your cave.
