I noticed a few years ago that the leaves had been reversed (like a photo negative) from when I remember them. The ones that they sold in the store were always "backwards" and you could tell the difference b/t the LEGITIMATE ones we got to the "fake" ones in the stores.
But now the ones the team uses are just like the ones in the store. Our leaves had a stem that curved to the RIGHT and a lower left blade that was more solid black, while the stores carried the green ones and some black ones that were opposite (stem curved to LEFT and lower right blade that was more solid). The current team also uses these now.
