The Black Diamond PIECES die comes with seven dies designed to fill in the spots of the Black Diamond (4x4, 3x4a+b, & 4x5) dies. You will no longer need to run your entire Black Diamond die through your machine- just select the piece you need and crop your photo or paper to fit the space.
PLEASE NOTE- The PIECES are intended to work WITH your Black Diamond dies. They do NOT fit the grid.
