The Memory Box Narrow Metal Adaptor Plate creates an extra-sturdy surface for the more intricate Memory Box dies to cut on.
This die works with the longer dies from Memory Box, such as the Delicate Vine Border, Flowering Vine Border, Cosmic Star Border, to name a few.
For use in most leading die-cut machines. Please check the user manual for the particular sandwich needed for your machine.
Use in place of cardstock shims or painters' tape as needed.
Size of metal shim is approximately 2-3/4 x 11 inches.
