Anyone seen these before: https://www.ebay.co.uk/itm/xbox-dev...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649 The seller claims that they are jewels from early Xbox devkits, but I have never seen them. Although I am not really that knowledgeable with Xbox stuff. Maybe they are prototypes? Or just custom jobs by a fan? Either way at the current price of $22.50 for the pair, I think these would be a good addition to someones collection.
