Hey guys I bought a pair at Japan Goods Finder . com. If you go there to the product section, they have them there. Very rare indeed. I hope this helps
Not interested in them, not at their current price anyway. Far too expensive for what they are, a bit like the Beams. Also odd that they were advertised as being only available at a conference for a couple of days and only one per customer and yet they are readily available from sellers in large quantities.
