Steve,
I'm not sure. These boxes appear to be fairly new and I have only received 2 or 3 shipments in their boxes. I can't even remember exactly who shipped to me in the Airliner boxes. I know I liked the bouncy cushioning effect and the ease of breakdown, with very little to go into the dumpster/landfill compared to styrofoam boxes. It is my feeling these boxes would be very good for shipping koi so I tracked down the supplier by posting a question on a marine BB.
To make the story short they found out about the post and contacted me. I don't have much need of many of the boxes, but I'm enough of a tree hugger that I would like to see these gain favor over styrofoam of which I am no big fan.
So Kevin Streva (Cold Pack Systems) wants to talk with me about the potential of koi industry. If anyone else is interested in these please let me know and I will ask Kevin to contact you.
Mitch
PS
I'll ask him which size boxes they make liners to fit and if they can beef up the cardboad they sell. Perhaps if there is enough interest they can design sizes for shipping larger koi more safely. Sure would be good for the show circuit.
