3. It features double-layer tempered glass (ordinary ones only have tempered glass on the upper layer, while the lower layer is ordinary glass). The light-storing interlayer uses high-brightness full-luminous aluminum plates, vacuum-sealed and laminated in a furnace, with waterproof and moisture-proof ratings up to IP68. The edges are framed with 304 stainless steel, making it aesthetically pleasing.
