Cold Pack 6 oz.


Cold Packs are used to help keep products, like live mealworms and yogurt drops, cool during transit. Add at least 1 cold pack in temps above 80 degrees, or 2 cold packs in temps above 90 degrees (multiply x2 for every 5,000 worms). Cold packs work with styrofoam packing peanuts to create an insulated "cooler" effect to keep the package cool for the first ~24 hours in transit, but they are not guaranteed to stay frozen in transit and they do not guarantee the condition of your product without Next Day shipping service.

*GUARANTEE: Your products are insured if cold packs are included and the order is shipped by Next Day service and the package is received upon delivery (or held for pick up). Signature service is available for delivery. Read more in .
