Abstract: This invention provides a printed and die-cut, new, three-dimensional ornament, (in this case an octahedron), that can be mailed flat, that pops up into its final shape without assembly by the recipient when removed from the included flat envelope. Manufactured from paper card stock or other sheet material. There are three glue flaps forming four equally shaped triangles on the top and bottom portions of the ornament, joined by a center fold. Attached to hook-and-ball finding at each longitudinal end is an elastic or tensioner which recovers the size and shape of the ornament after it is extended to fold the ornament flat. Ornament returns to its final shape once released from sleeve. This item is used to communicate with recipient by means of a combination gift and greeting or promotional message or advertising through corporate branding of ornament and/or sleeve when combined with ornament.
