Steel Boy II Thermal Mug 400 ml – Black
Black insulated mug with lid, 400 ml capacity, made of durable 304 stainless steel that does not absorb the flavors or odors of the beverages stored inside. The exterior is also coated with a protective layer that allows for dishwasher-safe cleaning, making regular cleaning and daily use easier. The mug’s design makes it suitable for use at home or around town, as well as for outings, camping, and summer camps.
Double-insulated walls and a convenient lid
The double walls, manufactured using a vacuum process, limit heat exchange between the beverage and the environment. The airless space between the walls ensures that the temperature of the contents is maintained longer for both hot and chilled beverages. The lid with a drinking opening reduces the risk of accidental spills during transport while also slowing down the cooling of the beverage. The cup is also equipped with a handle that makes it easy to hold comfortably during everyday use.
