Key Chain Caricature Shrink Art

I had been a long time I did not have a chance doing shrink art caricature for key chain under event company.Basically, the process of such art craft was using a special plastic, we just draw something interesting on the surface then put it in a small toast oven in few minutes, and this special plastic will shrink down 50% and became hard, hence it is suitable to put in a key chain ring to make it into an interesting unique key chain.
