Techni ICE ~4 PLY HDR 3 color model! How do you transport food safely? Camping? Picnics? Games? Current methods are of course a refrigerator in you have electric, but those of you who venture outdoors such as fishing, camping, back packing or picnicing need a more convenient way of keeping foods cold. Old methods include gel packs or dry ice. They both leave much to be desired. Dry ice is hideously expensive and hard to locate. Gel packs are only good for a couple of hours and they start to melt. Ta Da! New technology!! Techni ICE made in Austrailia is now available. The advances made by Techni ice are truly amazing! This easy to use product is purchased in a dry lightweight state and is hydrated by the consumer. Once well hydrated, it expands and is then frozen overnight. That's all there is to it. Place in an insulated cooler for use. You use several sheets to maintain a frozen state for DAYS. You use just a couple of sheets to maintain a refrigerated state, for DAYS! You can also pop one into your lunch box, bottle bag, or even backpack to keep things cool. The best part is, they are reusable!
