Thermal function: Hot stays hot and cold stays cold
On the ORNAMIN plates and bowls with a thermal function, the cavity between the inner plate and the outer plate can be filled with hot or cold water or crushed ice. This way, food stays hot (or cold) longer and gives slow eaters more time to enjoy their food. The ORNAMIN cups with keep-warm function also have a double-sided wall, but instead of water, the insulator is air. The air insulation helps to maintain the desired temperature of the liquids for longer, which makes drinking more pleasant.
