This is quite rare, and is a plastic cigarette holder for Camel Cigarettes  and stamped OSC for Oregon State College the name of which was  changed in 1961 to Oregon State University. This is from an Portland,  Oregon estate. This measures 2 1/4" X 2 7/8". Please look closely at  my photos for details.   It is marked Tupper and 'The Club' and is in good condition for its  age.  The plastic has hardened and yellowed but shows no cracks. These boxes were quite common through the 60's when Camel  filterless cigarettes were very popular.  They proteced the pack in your pocket from being crushed. This one is unusual because the Camel  name is in the maroon color of USC and matches the university name. Usually the word Camel was in blue or black script.  These packages  were sold at the university bookstore as a marketing tool.   Please see my store as I have another for sale from the University of Southern  California...
