From Dr Yun-Ching Chen: The "paper flower" that goes on the toilet for the Gut Zoomer collection is terrible. It would be easiest to include a cardboard tray, like the ones used at picnics. This is what is included in the GI-Effects and GI-Map test kits. It can even be made of collapsible cardboard if you want to continue using the tiny collection boxes. The other kit boxes are much bigger to accommodate the collection tray dimensions.
