ThermoGuard Insulated Paper Hot Cups protect your hands from hot beverages without adding a sleeve or costly double-cupping. Insulating air channels reduce heat transfer, keeping the side wall cool to the touch. Polyethylene lining on the double-wall construction acts as moisture barrier and keeps contents from leaking. Rolled rim provides additional strength to the cup and allows a tight lid fit (lid not included). Hot cups are SFI Certified and made with at least 92 percent renewable resources.
