Our .010" Mylar reeds (set of three) are marked with their top side (yes, reeds have a true top and a bottom side, and should always be placed in the call with the natural bend going up and away from the one board as you blow) and we feel have a little magic in them. They come in a nice snap case and have one Sanoprene rubber wedge, precut to fit (which is my favorite). Sanoprene wedges will never swell or shrinks like cork does, thereby never leaving you with an odd sounding call due to a loose reed, no matter how old the wedge is. Carry some in your kit for those times when you need to change your reed to suit your needs.
