Thanks for the input guys, right now I'm looking to order a kind of beginner BP shipping kit. My aim is to use this kit for shipping BP's ranging from hatchlings to about a year old. My goal is to order this stuff all at once to save some money on overall shipping costs for the order.
So far I have:
12x16 cloth snake bags
12x9x6 insulated shipping boxes w/ 3/4" foam
40 hour shipment warmers

Anyone know of anything I'm missing?

And just a couple more questions:
Does anyone recommend TSK or superior enterprise or any other company over another for shipping supplies?
Also do you guys feel the size of the bags and boxes would be appropriate for shipping BP's up to about a year old?
