The inner wall is finished by Mirror electrolysis, it reaches to HD water with safer drinking, and it's also easier to clean. The density of the inner wall of stainless steel is strengthened after thinning, and the thickness is only 0.08-0.12mm, which reduces the risk of slow infiltration and makes the cup body lighter at the same time. The gap between the inner wall and the outer wall of the cup body is controlled within 1.2mm, which increases the capacity, makes the thermal insulation performance more superior and durable.
