Jewelcase question

I was wondering if any of you know what kind of double cd jewel cases the Blackhole Recordings label uses. I have both DJ Tiesto - In my memory and DJ Tiesto - Nyana, and those are packaged in a 2cd jewel case that I havent seen before. When I open it it kind of looks like this | (a “regular” one would look like this ,,__). I hope anyone knows what I’m talking about, 'cause I don’t have a picture of it. I really like to know where I can get these jewelcases. Anyone? Or should I just contact Blackhole about this matter?
