Vesture Hot Packs utilize Microcore technology to safely keep your meals and food fresh and hot. The famous red packs for those old school casserole carriers are still available for purchase. So many people still use their casserole carriers for bringing their delicious meals to Thanksgiving, soccer games, and pot luck dinners! The red Microcore pack is easily heated in your microwave and is far safer than gel since it is filled with a non-toxic liquid. The elegant design distributes the heat evenly, but doesn't trade style for strength. The durable and flexible outer film can withstand over one ton of pressure! Place in any type of container for continued heating. The American family still depends on casserole carriers to contain and warm their meals. The fondest memories we hold are those of coming together over meals - the breaking of bread, sharing of wine, the communal process of preparing food for one another. Make sure your meal arrives right. Buy a Vesture Red Pack to ensure that when you get to your party and unwrap your meal, it will be perfectly ready to serve.
