This is a silicone inner tray. I had trouble finding it nearby and went to great lengths to get it, but it's no longer needed, so I'm offering it to anyone who wants it. It includes 2 regular size trays and 2 shallow groove type trays, for a total of 4 trays. While not easily damaged, it will be shipped directly in a cardboard box that is just the right size, without any protective materials. Shipping will be via Yu-Pack.
