For added protection when shipping temperature sensitive products use our PHASE 22 packs in conjunction with your shipping warmer.  

For best results please see instructions on back of packaging. Packs should always be wrapped in newspaper or put in a brown bag then put in your insulated shipping box. Can also be used alone in box if tight packing material is used around it. Packs can take up to an hour to begin to feel warm to the touch. Never tape over RED stripe that is where the breather holes are located.  Never place next to live animals or overheating and death could occur. 

Shipping warmers are not guaranteed to keep animals alive in all temperatures. Please use good judgement when packing live animals for shipping. You should always do your own testing on your packaging to be sure your products you ship are safe from the outside elements. We are not responsible for losses incurred when using this product.
