Can somebody post a picture of them wearing their half X. I want to see how big/small are they. There are a bunch of half x on ebay right now for a pretty good price.
This is the only picture I have but you can see their difference on sizes. I don't know where to put the Mars Leather so I put it in front. The arrangement of X Metals is not in order like what you have requested but I think penny should be the smallest, then Half X, R2, Juliet, XX, XS then R1
