My boyfriend (now retired) told me one of his friends used to bring Tupperware citrus peelers to work with him everyday for his oranges, and that his friend was always eager to show the other guys how great they were and how easy it was to peel oranges with them.  I had heard of them since about the time I first heard of Tupperware, and was skeptical.  But to humor my favorite guy I bought the 10 pack as it was most cost effective and who cares what color you peel your oranges with.  What a big surprise for me!!!  They really do make peeling oranges a snap, and the edges work great to scrape off the white (healthy but yucky) part I don't like to eat.
