The pressure of urban life continues to rise, and we need a cup in our busy life to increase the mood of life through a sense of ritual. Simple yet ingenious glass is the answer – a drinking glass that can serve multiple functions. Magnetic glass is used in work restrooms and business dinners. Precise calculation of magnet position makes switching from water glass mode to wine glass mode quick and easy. The lid of the water cup can be switched to the tripod of the water cup, and the simple structure provides the greatest convenience.
