There are many bubbles formed. The quality of the cast is not very good if you are looking for thin casts and also, th thick casts dopesn't bend smoothly. If you are creating cast for a chess piece for example, you'll have to use cut-out technique, as the rubber doesn't bend enough to take out the piece
