From the Infinite Hero Split Jacket OO9099-17 July 2011. Note: This one was a little bit hard to get ahold of on its own. Many of these SE microbags are not easily separated from their sunglass model, although it still doesn't hurt to ask just in case. I had a stroke of luck with an Ebay seller that just so happened to be selling one loose, and then for only $22. Things were good that day.
