The Kupo 4-in-1 Apple box set includes 4 Apple boxes in standard, one-half, one-quarter and 'pancake' sizes respectively, all made of a durable 9-ply Baltic birch wood. In addition to its innovative space-saving design, this set is ideal for storage and transport. The three smaller boxes of the set can easily be placed inside the standard-sized Apple box via a sliding side panel, which is fixed in place by two magnets.
