Impression Obsession Steel Die Set Ghosts This is a US-made steel die compatible with most table-top die cutting machines. The ghosts range from 3/4" to 1-1/4". Some of the more detailed dies require extra care to achieve the best results. Additional shims may be necessary and some machines handle the detail level better than others. If you are using a Cuttlebug with very detailed dies, we recommend using a metal adapter plate for best results. The metal plate also works well with other machines and the very detailed dies.
