The normal one is around 6cm effective using length. The short one is around 4cm and the longe one is around 7cm,
We also have an thing like an "bolt", this would conect all D-Rings together and there is no using space any more between the rings, so the bands are fixed together.
Ines And when are they used?
For the normal, i think there is no explay necessary, its for normal dayly use.
I can ask for the long ones if I'm not doing so well, or if there needs to be a little more space for some reasons, but the tight-bands should still be worn.
The short one and also the "bolt" is used normally as punishment. When rules are not followed, or if i try to cheat to the belt for example.
