None of our summer shipping test were done using freezer packs such as the ones you posted.
I would think as long as pollen stays dry and cold that this may work, possible rather well.
Having no experience with shipping with freezer packs, I'm wondering if the melting freezer packs over the time frame of the shipping would create a condensation effect that could render the pollen useless.
It sure would be interesting to find out though.
I hope that you can test this out, it would be nice to know if pollen could safely be transferred in season at a reasonable cost.
If it did work, I think the most economical way would be to get as much pollen as possible in one container, the freezer packs, shipping box, and whatever you use to protect pollen will be needed for each shipment no matter how many pollen tubes, etc are included.
