Designed for a variety of functions across the Holsim product range.

In the Bovine Artificial Insemination Kit, the bungee cords are used to adjust the position of the uterus and cervix to simulate different ages of cows.

In the Bovine Birthing Kit, they are used to suspend the uterus bag to make it easier or harder to birth the calf. It is also used to allow the simulation of a prolapsed uterus.
 
They can be used to adjust the tension of the cervix to simulate degrees of difficulty.
