I had these for a few months, they were cute little guys. I RAOKed them not too long ago to make room form shrimps but they're great little guys/gals.
When I sent my frogs to the buyer, I double bagged a ziploc and pumped air into it with my aquarium air pump. It then went in a styro foam lined box. It must have worked pretty well cause the package got delayed at the airport for 2 days and they still maid it.
