Origami-inspired pendant - "extruded boxes"

This pendant is inspired by a David Huffman origami later called "Extruded Boxes" - it inspired me because it captures movement and internal tension when partially folded. Medium: 24.5 x 20 mm. Large: 34 x 27 mm. Does not come with a chain - these can be purchased separately for a modest amount, e.g. see http://shpws.me/P3An
