These skin-care bottles are inspired by the shape of the letter U. The cap and body are both formed in a U arc and together they form a double-U shaped bottle. Along with its elegantly slim form, the bottle also pays close attention to ergonomics. The bottom of the bottle is inspired by a round root, a typical design in China for hundreds of years ago, which is able to steadily hold a vessel. The U-shaped interior bottom ensures that less product is wasted at the bottom of a bottle. All in all, this design considers both economic and environmentally-friendly benefits.
