Does anyone know where I can buy shipping heat packs and Styrofoam shipping containers for mailing my shrimp? I need something that can last a couple days. The best I could find was an 18-hour pack that uses oxygen. I remember there used to be a heat pack that if you flexed the metal disc inside, it would warm up good. I think those didn't need oxygen to work. Susan _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
