This innovative packaging solution uses environmentally friendly PET material and soybean ink printing. The box is very robust on the outside and flexible on the inside, thus protecting the enclosed energy-saving bulb from vibration and jolting. The wattage, brightness and colour temperature of each bulb is clearly discernible on the packaging, while the product is clearly visible through the window. An overall discreet look underlines the elegant design language of this bulb packaging series.
