This is one half of a set of scales for a 91mm victorinox knife designed specifically to print in aluminum. Because of the printing process, you can only do one side (scale) at a time, so rather than print both, you have to order them seperately. This scale will print in several other materials, but again, it is only one half and you will have to order the opposite side. If you want both sides in any material other than aluminum, please order one of the side sets, it will save you money. Thanks for looking.
