Can I reuse it? How many times?

* It depends on the prosthetic piece and what it's being used for. Some pieces are thinner than others. Each use will cause a little more wear and tear on it. It also depends how patient and careful you are during the removal process. That being said, here's what we have told people:

Film-A fresh piece for each shoot is preferred by most movie makers, especially if they are shooting in HD and are doing closeups.

Theatrical Productions-Depending on the length of the production and the actors, usually 2-4 times.

Haunters/Scareactors-We've been told that some scareactors have used their pieces 10-20 times. 

For the average user-We typically tell them 2-4 times. There again it all depends on how you remove and care for it.
