Double layer feature.- The vacuum between the two glasses prevents heat transfer and keeps the temperature longer.
It is produced by vacuuming a single piece of glass, so it has an extra durability. Despite its durable structure, it is very light.
It is beautiful and easy to clean, yet tough and durable. Made from hand-blown borosilicate glass, lighter and thinner than other glasses.
Not recommended to be washed in the dishwasher. Because the heat transfer between the two glasses can be disrupted and the glass's feature may be lost.
