Qibaiqi is a brand specializing in the production of sulfur soap, the combination of the Chinese word "Bai Qi" is the word "soap", thus reflecting the brand's focus and confidence in the sulfur soap category. For example, the name of Qibaiqi was arranged in succession to create a repetitive visual; Qibaiqi sounded like "seven hundred seven", which led to the idea of the Arabic numeral "770" as a brand mnemonic.
These inspirations were also incorporated into the shape of the sulfur soap during the packaging creation process. In both the basic and limited edition, the shape of the soap and the "770" appear on the front of the packaging to emphasize the intrinsic connection between the product and the brand. In the base edition, the shape of the sulfur soap and the frosted mirror filled with water drops are the central visual area. For the limited edition, the basic layout of the base edition is used to create the limited edition by weakening the core visual area and then creating a series of posters with the packaging as a whole to express the appeal of the limited edition.
