Hi i wondered why there are 3 different pairs of chains attached, if you can only use 1pair?

If i remember corect one was for arms one for feets and you could not mix them.

You can use any two pairs. One for arms, one for legs.

The physics isn't right, however, unless you use the middle pair for the arms, and one of the other pair for the legs.

To get her legs into the cuffs, just grab them and move them towards the cuffs until they automatically close. The upper shin area.
