Cosmetic outer packaging with a leather texture is a design choice that gives a luxurious and premium feel to the product. It involves using materials that mimic the look and feel of leather on the packaging. This approach is often used in high-end cosmetic brands to convey a sense of sophistication and exclusivity. The leather texture can be achieved through embossing, foil stamping, or even actual leather materials, depending on the brand's design and budget considerations.
