The skincare packaging box adopts a ‘double-door + folding fan’ structure. The outer walls feature a matte ivory-white specialty paper laminated with an anti-fingerprint coating, delivering a silky-smooth tactile experience. Both door panels are formed from 2.0 mm greyboard with 30° chamfered edges. When closed, magnetic closures conceal within the central frame, allowing effortless opening with a gentle push. The 120° opening angle creates a ceremonial display effect. A fan-shaped aperture at the door's centre features UV digital printing of gradient cherry blossom patterns. As the box rotates, light refracts through the aperture, evoking the ‘Light PRDA’ brightening theme. The inner frame employs gold foil stamping to outline delicate fan ribs, enhancing dimensionality. The base features a drawer-style insert with three die-cut circular recesses, securely holding the serum bottle and two ampoules with zero movement during transit. Perforated side walls maintain humidity balance. This fusion of Eastern fan craftsmanship and modern optical effects creates a radiant interplay of light and shadow upon opening – illuminating both the fan and the skin.
