• In order to improve heat retention, the inside of the double tube structure is evacuated.
• By applying "silver plating" to the inner surface of the glass, heat dissipation due to conduction, convection and radiation is prevented and heat retention is enhanced. (With Plating and Slit) - Special order available.
• We will adjust the bottom plate and height according to the filling and make it custom. Please contact us for details.
