These cutting plastics should be used with Long Cut and Extra Long Cut Studio dies. The Studio machine uses the cutting plastic between the material to be cut and the steel roller. Be sure to use the appropriate size of cutting plastic to match die board size. To extend the life of the cutting plastic, use both sides of plastic. Specially-formulated cutting plastic is part of the precision system that makes AccuQuilt Studio cutters and dies so efficient.

This product normally comes two per package, I only have one, and while it is well used, it still has life left in it.
