Cafe au Lait Mug

RIVERET is made from natural materials that have a lower thermal conductivity than ceramic, metal, or glass.

The reason this does not interfere with the taste of cafe au lait or latte is that the temperature of the container itself remains stable, regardless of the temperature of the liquid poured into it or the outside air.

The colors available are a luxurious white that makes use of the original color of the natural material, and a tasteful brown that has been changed by smoking it at high temperatures.
