Well, one of them is new. The inner one was one that I previously made. The larger one is a re-purposed cigar box that I got as a groomsman gift from a friends wedding last year. The box was collecting dust so converted it to this to get some real use out of it. Alone, the new tray is quite large. I knew I wanted my tablet inside the tray somehow, but adding the additional dice tray turned out to be a perfect way to keep my dice from hitting the tablet screen. Now I have a nice storage compartment, with a less-huge dice rolling area. I have used it for a couple sessions now, and it has been working marvelously!
