If there is one thing that I have learned is that nothing is ever 100% safe with any of the shipping couriers. I have personally had a very bad experience shipping tegus, twice no actually with two different companies. Unfortunately, it is hit or miss with the couriers now days. The employees don't care about package handling and carelessness on their parts leads to lost packages a lot. I own a herp business and bad shipping issues are plentiful and pathetic. Sorry if you were looking for someone to say that is safe to ship. Won't be me.
