About the stomata at the bottom of the double-layer cup:
There is a small air hole at the bottom of the double-layer cup, which is reserved by the craftsman in order to solve the instability of the pressure inside and outside the cup body during the production process. The glass cup can be used safely even in the case of sudden changes in cold and heat.
