1. Vacuum insulation identification method: Pour boiling water into a stainless steel insulated cup and tighten the stopper or lid clockwise. After 2 to 3 minutes, touch the surface of the cup body with your hand. If the cup body is obviously warm, it indicates that the product has lost the vacuum degree and cannot achieve good thermal insulation effect.
