Pushing open the door to the sample room, what caught the eye were neatly arranged vacuum bottles, like soldiers in formation, quietly guarding the secrets of skincare packaging. These vacuum bottles have delicate luster on their bodies, as if they can see the skin care essence to be carried inside through the glass. The lighting is a carefully designed soft white light that falls from the top and evenly covers every display area, making every detail of the vacuum bottle - from the bottle mouth to the bottom - clearly visible. There is a wooden table placed in the center of the sample room. Here, every vacuum bottle is not just a container, but a combination of technology and aesthetics, waiting to give skincare products longer lasting freshness and more elegant presentation.
