Use as the base for all other Impossible Box Add-on sets.
Start with this base box that is impossibly self-closing, add some layer shapes to embellishment and you have the start of a creatively, impossible box. Works with other Impossible Box add-on sets. Fill with treats and watch the fun begin when the top lifts up but not off.
Each set contains 5 thin metal dies. Assembled box measures 1 ½” x 2 ½” x 1 ½”.
