Zero on marking pins??
The zero for A, 1 for B, 2 for C is really messing with my brain as I have assigned 1 to 26 for alphabetical sequence All. My. Life. I gave three stars for giving four sets, in a handy case, with a non-pointy shape. I can't get over the weird-to-me numbering so I will be using a sharpie to erase one side.
