Oriboxi™ is the creation of origami artist and designer Paul Klenk of New York City. He coined the word in 2006 to trademark his business of designing and merchandising origami boxes and distinguish his brand. Curiously, at that time, a Google search of the word oriboxi resulted in zero results.

The word Oriboxi, a proper noun, is both singular and plural.

Klenk is also a singer and pianist, writer, and is fond of anagrams. He is an Executive Assitant by profession.
