Horse Science · Hoof Science anatomy models have been freeze-dried in a vacuum chamber at sub-zero temeratures for at least four months. This process removes all moisture, preserving soft tissue for a very, very l-o-n-g time. No chemical preservatives are used.

Proper care includes keeping the model dry, keeping it away from dogs, and protecting it from household insects (moths) with a commercial clothing spray or by storing it in a sealed container with an insecticide. Scratches can be repaired with clear shellac. There is one other hazard. Friends and colleagues will try to borrow your model; have them call me instead!
