The Tupperware orange peeler

Sledpress asked for a video of "l'ézesteur d'agrume" my wife uses for her morning bout with oranges, etc.   These little gadgets were given as door prizes to participants to Tupperware sales party some 40 to 50 years ago.  My wife got two at friend's parties.  One was yellow the other, shown above, liight grey or soft beige whatever you prefer.  The yellow one has vanished but we still have, and use this one.
