The Double Bottle concept enhances the tidiness of any shower, and not just the ones without sufficient storage surfaces. If you are short on ledges, however, you'll find this proposed product container especially convenient.
Bodywash, shaving cream and other bath-bound items quickly begin to clutter the place where you go to clean yourself. An easy solution is offered by Esben Oxholm Bonde, which is to put a pair of products into each piece of packaging.
The suggestion here is that shampoo and conditioner should be coupled together as a logical two-part duo. The Double Bottle takes up half of the space and makes the bottom detergent poised and ready for immediate dispensing. It's most efficient when you keep the emptier portion flipped upside down.
